1. The first part here doesn't argue against my claim that "blockchain is only good for evading regulation", it argues that evading regulation is sometimes a good thing. That's fine, let's set that aside.

2. The second part argues about centralized entities changing ownership. I don't think the example of Twitter usernames is a good use-case for blockchain: there's nothing here that isn't already solved by public key crypto alone (which is how blockchain solves the problem anyway).

Maybe Twitter here is just an example and you want to talk about corporate control over payment services? I don't think this is a compelling argument. There's no shortage of payment services and even if one of them is bad you can always find another. Yeah: Stripe or your bank go out of business tomorrow, but switching to Apple Pay or a different bank is not a huge problem.
