I took this as a rather astute but of roll playing that incidentally looks like it may address a serious issue. First of all since we are looking at over a year before the game opens up and some considerable time after that before there can be wars between settlements what else could it be?
Let's take a look at the land rush poll as Andius suggested though.

I see only 9 guilds with more than 10 votes (looks like ~10% of the backers eligible to vote have done joined guilds and done so) of those the top 5 are all pretty much guild aligned and have text on their recruitment pages that either states explicitly or suggest they are willing to help those outside their guilds and/or will fight evil. Of the remaining 4 2 are good aligned and one aggressively so. One of the others doesn't have a recruitment page and the other allows 5 alignments 3 good, 1 neutral, and 1 evil and goes on to say that evil acts will not be permitted in their territory. Now the numbers are likely to change over time but there's a pretty strong trend established.
Now look at the psychology of those that play evil characters. How many really want to be a minor cog in a large organization? On the other hand a lot of those who want to primarily craft or gather resources are content to be members of a good or at least neutral organization. I suspect we are going to see a dearth of powerful evil guilds. If one arises it's more likely to be an alliance of such guilds.
If we are to have massed battles and wars however it would be nice to see such organizations so getting a start on one now makes sense.
I will say I have seen some very well done recruitment pages by guilds that shall we say are on the shady side.
