I agree with what you wrote, but why does the US have be the same as those countries? Why can't there be a variety of implementations of government such that different humans can choose different situations for their own needs? I'd still like to see Cuba change to a fully democratic communist state, for example.
But when you discover that a system has way better objective outcomes, e.g. in the case of drug policy or healthcare policy, it’s a shame not to upgrade to a similar system.
Really, the US has a lot of good systems, but healthcare isn’t one of them.
I wonder if this is not an oxymoron. In my view, democracy means (a lot of) politics, while communism means no or very little politics (in a true sense of the word).
