You probably know this already, but people should have their own domain. Then they can change provider without changing the address.
If you're going to buy a domain for this, don't get fancy with the TLD. I made the mistake of choosing a .io domain for this purpose and with the future of the TLD uncertain, I have been moving away from it, so I'm not left in a bad spot if things go sideways.
People should, but is the existing process simple enough even any laymen can do is the question.
The average person is not intelligent enough to have their own domain.

Until they forget or unable to renew. And then their PII is in the hands of the person who gets the domain.
