Yes I agree, and the patrons of those ventures, perhaps all of society, could reap rewards in ways that go beyond a stock portfolio. It's funny that in the press release they mention "moonshot", because that's what we need. All of society puts in and all of society benefits. With measures and controls it could work, just like the moonshot did.
Yup. I imagine you'd be welcome and invited to stay for free, housing included, to many places around the world - if not everywhere. I do think in the future most everyone will have the ability, the benefit to travel anywhere in the world - as an incentive and reward for good behaviour; If you do criminal activity/counter-productive behaviours towards society or individuals, you lose that, etc..
