nft's don't poison the environment in and of themselves. First of all they don't NEED to exist on a proof of work blockchain, and second whether or not you make or trade nft's people are still going to be mining bitcoin and ethereum. your criticism here is of proof of work, not nft's. please don't conflate the 2. there are plenty of reasons that nft's are silly, but proof of work isn't one of them.
Until NFTs move away from proof of work I'll continue to criticize them.
It's like expecting good intentions and then being surprised when a few bad actors ruin things for the larger group. Tragedy of the commons is exactly why stuff like this should be called out, each and every single time.
