When I said "mostly gotten rid of monarchies", I include constitutional monarchies in that. The monarchs in at least most of those countries have approximately zero power compared with their historical antecedents.

If anything, they're a fine example of the kind of dealing realistically with our heritage I'm talking about. Actual monarchies have a track record I would generously call mixed, and perhaps more properly call horrific. But being half-evolved primates, humans seem to like having an officially recognized big monkey to rally around. So we keep the Queen of England around as something akin to a hood ornament on the car of that nation. It works, even if it's not particularly rational. But then, neither are we.
