Recently, I've been watching on-chain transaction replay, and the more I look, the more I realize that "cutting in line" isn't really about who is smarter, but about who holds the ordering power. The ones most affected are not the big players, but those who just click to trade with default settings: getting slippage eaten, distorted transaction prices, and thinking it's because they're slow. Many structures in DeFi actually assume they will be front-run; fairness is more like an option rather than infrastructure. By the way, I saw the community arguing again about privacy coins/mixing compliance boundaries, and it feels similar: the technology itself is neutral, but in the end, the usability for ordinary users often takes the hit. That's all for now; I’ll go revoke some authorizations on a few old contracts.
