On the carbon footprint: Ethereum will adopt proof of stake soon, of course you can trade NFTs on other chains but at least there’s an effort to drop the carbon footprint to very low levels. That’s more than you can say about most economic activities that have a large carbon footprint.
The scams seems like a very weak reason. The internet is full of scams, is the internet evil?
Ethereum has had "proof of stake" as a goal for multiple years, with no obvious evidence that it is any closer to implemented today than it was 3 years ago. I will believe Ethereum to be proof of stake when I see it.
The "kiln" testnet is currently running and will carry out the merge in the next few days, which is the final step before the existing proof of work testnets transitioned to proof of stake and then the Ethereum mainnet itself. I think that counts as "obvious evidence".

Apart from a working PoS beacon chain, several multi client dev nets and the last merge testnet before the real merge (barring major bugs) currently running
