There's also no reason that whatever it does look like would be better than that, or even that the "modern democracies" we currently have would actually survive.

I disagree. The biggest destabilizing force in the world right now is the US. The loss of American superpower status will make the world and its democracies more stable practically by definition.

You might argue that absent American military hegemony, Russia and China become belligerent. But the US isn't really doing much about either, so that's a moot point. All the world really loses is America's interference in their affairs, which I think the world can do without.

This is essentially a "something must be done, this is something, therefore this must be done" type of argument.

It's very easy, indeed common, for the "something" to be worse than the status quo.
