Hmmmm......honestly I wonder how taxation would work.
Currently, companies that do buisness overseas typically keep those profits in those countries (why pay taxes twice?)
I wonder if companies that eventually mine on the moon will be able to keep profits in foreign banks or have to bring it to their host nation banks
For those saying the US could just claim mars and no one would be able to contest it, please get a reality check. In reality, the US isnt actually trying to conquer or claim anything. Sure if it wanted it could probably conquer all of africa, but it would be a very stupid idea. Claiming mars would strain relations with other countries, bringing down the living standard through either war or economical sanctions. Sure you could destroy missiles other countries send to your mars or earth bases, and sure you maybe could defeat everyone in an all-out war, but such violence and war would never be supported by americans themselves. They wouldnt risk giving up their current comfortable lives and wealth and start WW3 over another planet. If it really comes to it, sure the US probably can destroy earth the most amount of times, but theres enough countries who could do it at least once. which is all that matters.
