Of course. Your capital gains would be taxed upon sale if you didn't leave; should fleeing the country allow you to avoid that?

Letting people take advantage of all the US offers while paying no tax on their growing wealth, and then letting them retire elsewhere without having put in their fair share makes no sense. Of course, we could stop taxing capital gains so favorably, as an alternative.

Even if it doesnt make sense to you, this is literally how the rest of the world works.

It makes perfect sense. It's just not the only viable or legitimate way to do things. As I said above: people are free to give up their citizenship. They'll pay the taxes that have been deferred (and then, only above a high threshold) and they can go about their lives.
