Monarchy is a useful construct. Obviously you wouldn't want it as a
system of government but it turns out humans really want some sort of living symbol, and a monarch gets you a random living symbol instead of the alternative of electing one (which both makes them subject to political influence
and even worse gives them apparent democratic legitimacy because people voted for them).
When I say random, what I mean here is that - while they're biological descendants of a previous monarch locking in some component of genetics - humans are enormously varied so what you actually get isn't so different from if you stole a random newborn baby. Fat, tall, slow-witted, ugly, it's out of everybody's hands. They didn't ask for the job (you might want to at least make it possible for them to decline - if they feel they cannot do it, but this decision must be strongly discouraged and irreversible) but it's not onerous and somebody needs to do it.
I think it's actually desirable for a country to find themselves a monarch, giving said monarch of course absolutely no actual power whatsoever, and some merely ceremonial duties. The people get a symbol, untainted by the day's grimy politics and the politicians can get on with something useful.
Now, would Andrew Lee make for a halfway decent King of Korea? It seems dubious, but unlike running Freenode it wouldn't come with any actual power. However the big problem, as with Freenode, is whether people accept him. If the Korean people recognise Lee as King, why not?
