Most people want a way to recover their account if they lose those creds, especially when you ask them once they’ve lost their creds.
It’s also a rudimentary PoW system against bots. And people who don’t want to share their email can use a temp email service, so it’s no skin off their back.

That seems to be a better option for bots than for actual users: if you care about the account, you probably would not want to make its password resettable via a service like that. Or even via a regular email provider you do not trust, and those could easily be the only kind available.
Ultimately this is akin to password requirements. They are a bother but the average user is just much too careless to be trusted with their own security.
