It was a commodity from the very start, but the regulator doesn't want to accept that as they don't want to accept bitcoin as a commodity either. Banking sector and people who run them felt threatened by the very existence of bitcoin and ETH. They are the ones that pushed the SEC not to accept bitcoin or ETH but as this industry got bigger and stronger, they had to accept it. Everything is becoming tokenized thanks to the smart contract technology developed by ETH that makes this possible. Bitcoin and ETH are the two greatest innovations of this century.
Ethereum WAS a commodity when it was a PoW coin. But not anymore. Especially after switching to PoS. You basically become a shareholder of the network by holding ETH on your wallet (otherwise known as staking). In return, you receive a compensation (interest) depending on the number of coins you've deposited and how long it's been on your wallet. The longer the time, the higher the rewards will be. Similar to stocks that pay dividends.
The SEC only changed its opinion of ETH after pressure from giants like BlackRock and VanEck. After all, money talks. I hope Ethereum takes decentralization seriously before it's too late. You can see why no other coin can beat Bitcoin in terms of decentralization and censorship-resistance. It's what we need to obtain true financial freedom even from oppressive governments. Who knows what will happen in the future?
