Just to get into low Earth orbit, you have to jump through so many U.N. hoops that you feel like a circus seal. The forms alone are enough to dissuade most people with only a casual interest. To get to Mars, where the embassies are, there are background checks and personality tests and blood tests and twice as many forms.
To get onto a Polixaci liner, you need all of that, plus a small fortune. To actually stay on the liner as a passenger when it departs for other systems, you need a large fortune.
I’m thinking it’s worth it.
