Being anti-crypto like this is similar to being an anti-vaxxer for tech. You’re analysing everything through an ideological reality-confirmation bias instead of acting like a scientist and looking for the truth. You don’t want something to be true because you don’t like mRNA/Bill Gates or Bitcoin/Libertarians are at its origin.
Instead you should face the truth that this is a marketplace for digital art and that it works. Far simpler than concocting wild theories about 5G or NFTs being performance art.
It just works, it’s real and people are using it. Saying “NFTs have no value” is like saying “Bitcoin is not money”. It has been the equivalent of money for 10 years now, so when are you going to give it up?
