The Flashbots MEV Auction as a scaling technology framing is great and something they have been saying for a long time.

It doesn't tell you spam is bad if you can build the capacity -- but it does make you think on your levers to scale.

It gives you one more lever to scale via offchain systems and get the market efficiency you want without doing diminishing returns systems optimizations (bad ROI on time eventually) or consensus concessions which may compromise your open source-ness (bc MEV validators abuse the ordering as much as possible to make money), or your network topology and geographic decentralization.

Similar to how scaling pre training gets harder and harder from here, and you look for other places to scale which are earlier in their sigmoid eg like post training RL.
