The other thing about punk is that it's really more an attitude. Some punks are really skilled musicians and lyricists that bring a lot of outside influence into their music.
Punk is so interesting in his variations. Compare with metal where speed, black, alternative etc are quite coded and baroque, whereas punk still manages to stat fresh.
I think while there are plenty genre that requires more skill than punk, that doesn’t make punk itself the musical equivalent of simpleton.
In some aspects, it’s the artigianal counterpart of the mass produced pop.
