Maybe I’m wrong, but I’ve always looked at punk (the music, not the ideology) as a thing that was, not is. Similar to classic rock. As in… there are no new classic rock bands. No one says, “hey. I’m forming a classic rock back and we’re writing all new material!”
Punk was The Ramones, The Dammed, The Sex Pistols. Black Flag, The Clash, Dead Kennedys, etc.
Just like how classic rock was Led Zeppelin, Pink Floyd, BOC, Rolling Stones, The Beatles, etc.
Again, many will probably disagree, but this is simply an opinion on the matter.
