Donald Trump doesn't like the whole concept of government of, by and for the people, the idea that political power derives from the will of the people rather than gods or kings or priests or…dare we say, political strongmen, real and imagined.
Archaic means "old-fashioned" and "obsolete" and "out of date" and, perhaps wistfully here for would-be dictator Donald Trump, "no longer used."
You know, because we have this whole thing about three co-equal branches of government and checks and balances that prevent the president from ruling like a king – or a Putinesque banana republican dictator.
It's inefficient, he says. In other words, he's frustrated that he can't do anything he damn well pleases without appeal to all those pesky and inconvenient laws. He can't try to rule by fiat without somebody saying "un-Constitutional!"
