Plenty of people don't even type their email correctly. Ask anybody that runs a service and sends email, then you'll see. E.g. "myname@domain.com" vs the typo missing the final 'm' "myname@domain.co" But I do agree it's rather annoying and not allowing paste is even worse. I actually trust my copy-and-paste more than me not making a typo because I am human. By not allowing paste, websites are asking me to potentially make mistakes. Perhaps a better solution is for the browser to have a button on <input type="email"> fields to allow me to select from a list of emails I have. The browser needs to protect this data from being website accessible until I give permission for privacy reasons, but that would have been a way better UX.
