In order to protect astronauts from decompression, the hull of a spacecraft has to be insanely good at stopping gas particles. Not 99.5% good, but like 99.9999999…% with 20 zeros! That’s very good.
But a thin metal sheet has no trouble doing this, as demonstrated by the Apollo lunar lander.
Some things are just not as hard as they sound. Magnetic confinement works very well. It easily achieves the necessary 9’s.
It’s just hard to keep it stable at millions of degrees, but that’s a different problem.
