Sarcasm doesn't carry well on the internet.
But honestly, if they have lost their email account (or let it get trashed and deleted) or they can't remember their credentials, they can set up a new account. If... and that is a big IF... they can later confirm that their old account is the same as the new one, I may merge them.
But sorry, I'm not going to simply reset someones password because they tell me "hey, I don't have my old email any more and I don't remember what my password was". No, my site does not have national security secrets on it, but I do owe a level of security to my users. Social engineering has been a thing for years and years, and admins of websites are no more exempt from it than anyone else.
The point was if they were a prolific user (or even a regular user) and had to go away for a while and then forgot their password and their old email was no longer valid, how exactly are you going to confirm they are who they said they are if they want you to manually change the password and give it to them or change the email. To simply do that without due diligence worries me more than having to send in a scan of my drivers license that can be checked. If they want to continue using the old account, they are going to have to confirm that they have the right to, and sorry, I'm not going to take the "just trust me" routine. Many a young lady has found out that was a path that they probably did not want to walk.
