Space will kill you in any number of ways. So, in fact, will most planets that aren’t your homeworld or close copies of it.
Simple risks will kill you, if you don’t keep a weather eye on them. Radiation, vacuum, dioxide, heat. Leaks, breakdowns, inefficiencies. Not paying attention to where your air and water and other things that just magically exist for the taking downside come from, that’ll kill you, too. Carelessness, inattention, expediency, pragmatism, shortcut-taking, an excessively casual approach to maintenance procedures – all things that bring an automatic death sentence at the hands of the uncaring, pedantic universe. Incompetence, determined ignorance, and native stupidity, even more so. And indulging one’s fond delusions about the nature of reality, that’ll kill you fastest of all.
These are the reasons why many sensible people from many sensible civilizations choose not to go there.
The people who scattered habs across the entire system from Oculus to Farside, from Eurymir to Galine, from corona-scraping Salamandrine to lonely Blackwatch, on the other hand, considered these things advantages.
