Reading this, I almost feel like Gnosis is doing a better job at bringing home the Ethereum vision than the EF and Flashbots. How much of MEV is fixed by this and what is stopping Ethereum from implementing it?

I don't know enough about MEV to tell how much it can fix it but Gnosis is def treating this problem seriously since CowSwap. Since Gnosis is Ethereum's "sister chain", I imagine the EF team could follow the R&D done by Gnosis and - if it works - at some point implement it on Mainnet.

Gnosis is the most pragmatic and practical chain, yet retail doesn't get attracted. Not sure if its good for it long term or not, maybe if they had one memecoin, retail new they exist, but culture there not fit for it.
