Definitely.  To date we have not solved the radiation thus cancer problem.  Until we do, gathering enough assets to be self sustaining is the least of problems.  We are unable to go beyond Earths protective magnetic fields save relatively short expeditions.

Ozone layer. The vessel would need a layer of ozone between the areas for living or working and the outer shell of the satellite. A big problem: ozone is dangerously toxic and reactive.

The problem is deep space, where charge particle bursts from solar flares are actual killers.  So far, the only option is a lead-lined chamber that holds all the travelers -- assuming they can accurately identify every burst well in advance.  Unfortunately, gamma bursts, which are less deadly but still really bad, give no advanced warning.  Then again, the lead-lined chamber is only a partial protection anyway.
