I think there's a good argument - made very well by Viv Albertine of The Slits in her autobiography Clothes, Music, Boys - that people outside the scene took punk too seriously. They weren't great crusaders for truth and justice, they were the court jesters who pointed out the emperor had no clothes but were mostly just having fun provoking people. Which includes John Lydon pissing people off by issuing NFTs and praising Trump. It's all the same.
The Sex Pistols were a boy band, Lydon had a brief window of authenticity with PIL but has, in the last decade or so, become a caricature of himself, to the point of endorsing Thatcherism. Lydon today overtly rejects what he ostensibly "stood for" in the era of the Lesser Free Trade Hall show. You couldn't come up with a better illustration of how un-punk crypto is than a Johnny Rotten NFT.
