Pragmatically: It depends on the country’s laws for free speech and criticism, your location, and a country’s extradition relationship.

Personally: Yes, we should all have the right to criticize our own and others’ governments. But we should also take the responsibility and initiative to get educated while doing so.

One tip would be to use email addresses that you actually check for mission critical accounts.

Probably some mix of: it was an unknown and unregulated industry when domains were invented, the idea of ‘property’ doesn’t really work like that IRL (the bank or local government can take your house for myriad reasons), and people aren’t motivated enough to make any significant changes.

These days, I don’t remember the last registrar I’ve seen that does not provide at least some kind of basic hosting. Maybe they want to grow like all businesses, maybe just being a registrar doesn’t keep the lights on anymore. Not sure, but it definitely seems to be the thing most, if not all, do now.
