For now I just want to comment on one piece, this meme that NFTs are killing the planet through consumption of insane amounts of energy is silly and falls apart with a moment's thought.
All estimates of per-txn energy usage take the total number of transactions and divide by the total energy usage of the chain. However... bitcoin (and other chains) happily consume a lot of energy even when no transactions are being processed. The more important question is: when you make a transaction how much more energy is consumed than in a counterfactual world where you did not make that transaction.
This number is very difficult to estimate, but seems to be at most 10kwh, or as much as driving your tesla ~30 miles, or running your dishwasher 5 times, or running your air conditioner for 5 hours, or doing any of a number of other things which people happily do every day without thinking twice. It would be nice if energy consumption was much lower, this is a non-trivial amount of energy, and multiple chains are working toward lowering it, but popular articles all seem to believe your NFT could power Berlin for a day if only you weren't being so selfish.
