I think your point is that, as long as there's an on-chain incentive to mine the most profitable transactions, then the most profitable valid transactions will find their way into blocks.

I don't disagree with that, but my question is at what cost and at what degree of usability? I think censorability is a spectrum, not a 1 or a 0. So my argument would be that bitcoin's built-in incentive structure can keep censorship<1, but it's uncertain if it can maintain a high degree of usability and mainstream adoption.

So, I still maintain that social norms, ethos, and other soft crap like that still matters for the tradeoff matrix between censorability and usability on bitcoin
