My argument is there are contemporary bands that call themselves punk and are called punk by others. There are subgenres like pop punk to further clarify. One could be a cliché pedant and say like “pop punk isn’t punk” but that was an eyeroller when 30 years ago when the argument was new.

You said “a lot of them” on the search link can’t be called punk. But then some of them presumably can be. So then new punk bands exist.
