Own domain and hosting have their set of issues. Like how to make sure you don’t loose your domain to attacker due to phishing attack against your registrar support person.

If you are just an individual you may have difficulties in proving your ownership of a domain in case you loose it.

Don't shift the goalpost please. We are talking about forgetting password for your email account.

Now the part about attacking your email/domain:

If somebody transfers your domain without your will you have to contact domain registry and you will get it back after a bit of back and forth. It happens, noting new here.

Unless you register .eu domain - there is a whole institution dealing with that and there is no easy and quick way to transfer the domain in a stealth way + long grace periods and better authorization so its much harder to even try to do that.

Compare that to Google - your account gets locked or even worse somebody gains access to your email and that's it. Your not getting it back.
