The ISS's inflatable activity module is definitely a Starfinder kind of thing

After A Year In Space, The Air Hasn't Gone Out Of NASA's Inflated Module

Bigelow Aerospace wants to make a whole space station with this technology. Bubble compartments made of reinforced cloth and fabric linked together sounds like something you'd see in Spelljammer / Starjammer or Starfinder, wouldn't you say? Probably cheaper than boosting a whole lot of metal and plastic into orbit, anyway.

Build one big enough and you could make yourself a self-sufficient bubble greenhouse (under spin gravity, of course). Grow some fresh food and sell it at a good price to all your fellow orbiteers that can't afford to bring up their own food from the surface.

I like the idea of using it to change the size of a ship on the go. Inflated it is a large leisure ship with room for activities and plenty of living/sleeping spaces, but can deflate and tuck all the excess material under the hull of the ship to travel at high speeds or enter combat.

I want a blow-up space station. I totally would live in one. You don't need gravity to grow vegetables; just use aeroponics.
