I think most people missed the point of the question on reddit. It isn't why NFTs are a bad idea. Let's be honest, a lot of collecting is a bad idea. Financially, ecologically. OP's point is that everyone, collectively, started having a deep hatred of them overnight. And I'd attribute it to a few articles and to Twitter groupthink now saying NFTs are the approved thing to hate on. Then all the cool kids must hate on NFTs, regardless if they use less energy than Magic the Gathering cards or trade for less money than any other collectible junk.
