The most annoying thing about punk was its elitism as to all other types of music. The most pretentious prog bands in their mothers' gowns never claimed that their music was the only thing worthwhile to the exclusion of everything else. Punk reeked of musical insecurity and intolerance.
I see that, but I'd argue that much of that is a) warranted (alienated youth and music that didn't speak to them at all - the kids to this day, e.g. yours, say the radio/top 40 is shit and how seriously do you take that?), b) due to the first wave of punk being, on average, not even legal (i.e. to drink or age of majority etc) when it started, and c) under attack/criticism form all sides. Yeah they were a bit immature and self-righteous.... but so was (mostly) everyone else at that age (except nobody was documenting it). That and many of those glam bands were just as elitist, just had the sense/lack of cahones (foolhardiness), to not go around talking shit about it like the Bromley Contingent (for example) would.
Despite your lack of intended insult (none taken, I ain't them), calling The Ramones more bubblegum not punk makes no sense to me (no 2 bands in the first wave sounded remotely similar, so what is exactly the "punk sound?" ... and also The Ramones schtick is the stylistic basis for what became hardcore and most of what is now classified as punk). Sure "chewing out a rythmn on my bubblegum" etc (a classic, awesome line by the way) and they were very comic book (even to the point of being actual comic book characters, literally, see below) that was never incompatible with punk. Punk, as the Ramones saw it (if Do You Remember Rock n Roll Radio can be taken as a manifesto) did look back to what was seen as the golden age of rock before all the perceived indulgences crept in (including the start of the popification of rock - aka bubblegum). Bubblegum implies lack of substance, and though there is a bit of a paradox at play (that revered golden age had some of the most banal lyrics ever) The Ramones can hardly be accused of that (on a consistant basis - they took themselves unseriously enough to allow the odd sappy love song or fun song, in between the more socio-political ones).
Those protopunk bands (I believe now classified as garage or glam, sometimes both, depending on which and what stage of their career; music stores were not as imaginative with the catagories back then I suspect) you mentioned, Iggy/Stooges specifically, were very influential in one way you are ignoring - being over the top and (trying to) make people wonder if they're taking you too seriously. Iggy self-mutilationg in ways that didn't (usually or intentionally) cause much more than superficial damage, but created a right bloody mess vs being snooty brats - because that's what the.... I dunno what to call it, establishment/adults/moral majority, thought of them so they owned and hyperbolised that actually elitist attitude as a form of satire - see Siouxsie with the swastika armband and the resulting controversy.... not that I think she should have done that, it was stupid, but she was what, 17 at the time, and had all sorts of media already crying out to burn her, some more specifically than others, at the stake; nothing to loose).
This elitism was a self-defence mechanism. Not necessarily a very good or mature one, but nevertheless.
Also there's footage of (I think) Queen (or was it Roxy Music?) dissing the shit out of the Pistols (after, I think, a bit of a scuffle that saw one of the Pistols get a good clocking; they were in the same studio recording their albums), so guilty all around.
