>That seems like the flaw here, not the other thing. Why should the US government have any entitlement to tax activity that occurs entirely outside their jurisdiction?
Tax evasion doesn't cease to be tax evasion because you don't feel like you owe the government taxes.
Whereas it does cease to be tax evasion when it literally isn't tax evasion, it's tax avoidance. And then people are complaining about this as if it shouldn't be possible, when it should be the default. To owe a jurisdiction taxes you should have to be doing something in it.
