but Bitcoin does nothing to prevent custodial exchanges, in the way something like Monero does

In what way does Monero prevent that?

I think some of the arguments are quite flawed. Bitcoin itself has most of the properties it is said to have, but it lives in a world that doesn’t and so some only really apply if you manage to stay inside the system. Like, your Signal chats are private as long as you don’t copy-paste them to Facebook.

Regarding self-custody/decentralization and using custodial services: The problem here is not that those properties don’t apply to Bitcoin, but that some people just choose to give away control over their wallets or not use Bitcoin itself for certain transactions. Can’t blame that on the currency, unless you think it can’t be done any other way.

Regarding privacy: I don’t think any serious “Bitcoiner” advertises Bitcoin as private. The message has always been that it’s “pseudonymous”, that you have to take extra steps in order to make it anonymous, and that it’s transparent instead of private by design.

Regarding transparency/inclusion: These paragraphs actually argue about privacy again. One is trying to spin the existing transparency into a negative, which is a valid opinion but not something “Bitcoiners” are wrong about. The other circles back to the idea of staying inside the system. Bitcoin transactions are inclusive, but ofc you can still get into trouble if you have to fear external repercussions and can’t stay anonymous.
