"The only alternative to a king or queen in a parliamentary democract would be someone who actually wanted the job". Not so - they could pick some poor sod at random and say, "we expect you to do it, whether you want to or not".

Of course, in one way of looking at it, that's what we've actually got, except that the poor sod gets picked at birth.

I can't actually see how bureaucratically getting rid of the royals would make any significant difference whatsoever.
