So, it would've been nice if he didn't come back from space, ever? Maybe the other people up top could've gone and stayed too.
Also, it's already a big thread on twitter, no one willingly stayed on space for more than a year so far - zero g, muscle problems, radiation, it's all still there in the best parts of the current space stations. If it's horrible for people who trained their whole lives to become astronauts, no, rich guy who never had a problem in his life isn't actually going to live to see a colony he'd want to stay in.
