A country can't just "decide" to have a king, at least not very successfully, because no one short of a king has the legitimate power to confer kingship on anyone. A country either has one or it doesn't; and those that do, have one because they've pretty much always had one going back to the days of tribal chiefs and warlords.
The U.S.Constitution provides the best form of government for us. We need to get back to it (minus some irritating amendments), not further away from it.
I think the mob can delegate its legislative power to one man. Ussually thats disasterous historically I agree because the worst type of people tend to get elected. The good thing about an old monarchy no real elections.
Right. We need to put the majority back in its box. The best way to do this: VOTER COMPETENCY TESTING! If you don't understand the Constitution, you should not be permitted to vote.
