1. If you consider the loss of a phone number to be a more likely event than a forgotten password (non-obvious example - if you have no extra money to keep the phone number working).
2. If some powerful contractors can capture the data coming to your phone.
3. Also, if there is some kind of banhammer (Google is famous for banning for no reason) in the "2-factor" and no banhammer in the 1-factor (Bitcoin has no third-parties who might steal or freeze your funds), then your chance of encountering a banhammer in your face is infinitely greater in the first case.
More than 1 factor creates more problems than usefullness tbh if you are enough responsible for never lose your credentials.
That's silly. If you lost your phone number, why would you attempt to log into a service and have it text or call your lost phone number? The provider in question here (along with many others), Google, provides backup codes for this situation. Besides, if you are more likely to constantly lose phone numbers, it's best not to use those for authentication/authorization.

That doesn't matter to 2-factor. That "powerful contractor" would be in possession of a time-bound pin that can only be used by the device and account that had just had the credentials entered. It is useless to anyone else.

This also doesn't apply. Google provides backup codes that can be used in such a case. As do digital ocean and others...

Except that isn't true. I noticed that you placed 2-factor in quotes, showing that you likely do not understand 2-factor is formed from any two out of the three possible security factors. There is also 1.5 factor authentication, which is acceptable to put in quotes, since it is pseudo-2factor.
What you know. What you have. What you are.
> (Bitcoin has no third-parties who might steal or freeze your funds)
I'm not sure your comment was serious... Bitcoin and the entire crypto ecosystem are full of third-parties who steal or freeze funds.
To be more specific, if the implementation of 2 factors requires both factors, then it is indeed more secure. If it's a form of 2 factor that requires only one factor, it's less secure, because now you have more attack surface.
