Recently, everyone has been arguing about Layer 2 in terms of TPS, transaction fees, and subsidies.

It feels a bit like only paying attention to "how wide the road is," but no one asks "who is cutting in line at the intersection."
As for MEV, it's really about who controls the ordering rights:
You think pressing confirm puts you in line, but you might actually be squeezed, jumped ahead, and the losers aren't necessarily the big players; more often, it's ordinary users whose slippage and transaction prices get worn down.

What's more subtle is that many people discuss "fairness" by default assuming on-chain transactions are first-come, first-served,
but as long as the ordering can be auctioned or privately coordinated, it becomes "who's better at negotiating."
I don't think it can be completely eliminated either; it can only be made transparent by exposing the rules for cutting in line,
at least letting people know what kind of game they're playing...
If someone has data to refute me, that’s also fine.
