1. Launch is the primary driver of (and obstacle against) all space activities.
2. Physics is philosophically opposed to space flight. (and so launch is the obstacle)
3. Nothing ever works the first time you try it. (and so launch is the obstacle)
4. There is never enough time or money to do everything you want before launch. (and so launch is the obstacle)
5. Fear governs all decisions.

Physics isn't opposed to spaceflight. Physics simply doesn't give a damm whether you make it to orbit or explode in a bright fireball.
Physics may not be opposed, but Gravity is, and so is Entropy.
.
1) All launch does is get materials and personnel into space. Lack of gravity is the primary obstacle against the majority of space activities. On Earth we have gravity to help us do work, in micro-gravity (space) we have to provide our own counter-force to do proper work. i.e. turning a screwdriver in micro-gravity results in the person and object turning in counter directions and canceling out any work being done.
2) As LazarX said above "Physics isn't opposed to spaceflight. Physics simply doesn't give a damn whether you make it to orbit or explode in a bright fireball."
3) A good rule for rocket experimenters to follow is this: always assume that it will explode. — Astronautics, issue 38, October 1937.
Taking this to heart launch only proves to be an obstacle if you are using a spacecraft that is launched from the ground into space. If you just send materials and assemble in space no single launch failure will result in failure of the spacecraft.
4) "There is never enough time or money to do everything you want before launch." is true but your conclusion is flawed. The only time launch would factor into construction time and cost is if crew training, general safety and construction of the launch platform and/or spacecraft were sacrificed to save time and money.
5) Fear doesn't govern anything in space travel, safety and efficiency governs all decisions but because humans are fallible and subject to hubris even those two primary governors are often overlooked or ignored.
I read the OP and immediately thought this was a yellowdingo thread.
Imagine my disappointment when I learned otherwise.
"String theory invalidates space flight!"

Because it was in someone's PowerPoint presentation, it MUST be true.
Mangoes in shipping containers dreaming of wind turbines.

Believing something is true based upon a PowerPoint presentation is pure bad reasoning.
Wow, you're way dumber than I thought you were.

Ah now come on Wizard, I know that's not true... you generally think everyone else is far dumber than they really are.
It's not my fault, it's the public education I got while attending private school.
That or my education about privates at public school.
One of the two.

The Five Laws of Spaceflight
1st Law of Spaceflight: you don't talk about the laws of spaceflight!
2nd Law of Spaceflight: YOU DON'T TALK ABOUT THE LAWS OF SPACEFLIGHT!
3rd Law of Spaceflight: if a spaceship blows up, the flight is over.
4th Law of Spaceflight: only one spaceflight at a time.
5th Law of Spaceflight: no shirt, no shoes, no flight!
5) Fear doesn't govern anything in space travel, safety and efficiency governs all decisions but because humans are fallible and subject to hubris even those two primary governors are often overlooked or ignored.Actually the entire American space program until 1969 was driven by the fear that the Russians would be the first to build an atomic missle base on the moon or perform a manned landing on it, claiming the globe as a Soviet Republic. The pulp literature of the period was full of it, although it was usually hidden "Space Nazis" who would take the place of Russians as the given bad guys.
Given the state of the American rocketry program as opposed to the then current Soviet successes, JFK's pledge to a moon landing was definitely a statement of boldness on his part.
Then why did NASA use animals for the first test flights? Human safety is why. The politics of the space program were fear based but NASA's first rule was safty. Safety first even though it cost them the goal of first man in space, first man in orbit and a few other firsts because it wasn't safe enough for humans.

Ok smarty: if gravity is the force pulling the planetary mass toward centre why is there a simultaneous force pulling at the centre of the planetary mass? Why are both forces 'gravity' because they are both created by the mass? If they are not, then is our assumption as to the nature of gravity wrong? What is gravity?
It's the weight of mangoes in superposition pushing down on us.
And now they are talking Sustainable Human Space Explorarion. Hahahaha... do you want fries with that?

Given they belittled private colonization, and painted Mars colonization in 'science only' colours are we going to have a problem?
One of the advantages of a lunar base is that if we set up ice collection and H2O splitting facilities we could actually manufacture fuel on the Moon (as well as collecting water supplies). That could save massive amounts of weight for an actual Mars mission, while also allowing us to improve our long range/duration capabilities.
The Moon isn't just some sort of baby step, but could actually be a critical and necessary step. It would also be a critical facility for testing protection from cosmic rays. A Mars trip would be at least ~300 days spent outside the protective shields of Earth, which means a lot of radiation. Much of which we don't even have a method of shielding.

Perhaps we do. You understand that a magnetic field has two poles. Consider this: the n-polarity is equal and opposite to the s-polarity. So let us create an unequal polarity where one is greater than the other. Distorting the field means a difference that can capture particles.
There is only one law of spaceflight.
To the Gnomes I became like a Gnome, to win the Gnomes. To those under the law I became like one under the law, even though I myself am not under the law, so as to win those under the law. To those not having the law I became like one not having the law, even though I am not free from the Law of Lights, but am free of the Empire's laws, so as to win those not having the law. To the weak I became weak, to win the weak. I have become all things to all people so that by all possible means I might save some. ~Book of Leafar 9:20-22

You aren't the first person to think this.
Currently, we don't possess the technology to do this... in space. A magnetic field is still going to require a lot of equipment and take up a fair bit of energy to maintain. There are a whole host of issues to fix to make it work in the confines of a ship.
Side benefit, I suspect that such shielding will provide some significant advances in superconductor technology.
Actually, I think yd may be the first person to propose using magnetic monopoles as a practical form of radiation shielding.

I'll give him a pass on the specifics and instead focus on the aspect of magnetism in general.
