I agree with your latter point. Fully out of country[0] citizens and maybe permanent residents after a certain amount of time. But not the high flat tax thing.

I agree with your latter point. Fully out of country[0] citizens and maybe permanent residents after a certain amount of time. But not the high flat tax thing. For the income portion of my compensation, I pay around 50% and it's not bad. With a UBI and a flat tax we don't have to make exceptions for married couples or non-married couples. The marginal dollar is always taxed the same. And if you're making, say, $60k a year that would be $42k after the UBI so the effective tax rate is 30% which seems reasonable. [0] There have been years where I was out of country for long enough to not have to pay taxes to Canada if I had been in one spot, but I'd moved around enough not to qualify to pay anywhere else so I was still paying taxes to Canada despite not being here for a while. Common enough digital nomad thing.
