@doomsdayrs Money is just one of the issues. You'd have to leave everything and, more importantly, everyone you know, your whole social context, behind.

It's not easy to do, especially when you're an adult with friends, family, romantic partners and responsibilities. You can't just pack them all up with you, as they have the same problem, just one level down. And if you don't have the means to travel frequently from one country to another, you might just as well leave for another planet. Sure, electronic communication exists, but it's not a substitute.
