Maybe ETH should focus on solving their scaling so the layer 1 doesn't cost arm and leg to do transfer on. Layer 2 becoming expensive as well and people already talking about Layer 3.
However, Ethereum L1 is supposed to be the settlement layer for rollups, and high security requirement transactions, not for shitcoin trading.
Recursive rollups (L3s,L4s) have also been talked about for years now, and it should be pursued; that's how you can increase transaction throughput and decrease fees with the magic of zk.
