The onus is on you here… but, I think I know where you’re going with this. In terms of number of email addresses people have and use, vs number of usernames people have and use, you might be right that some people have 1 or 2 email addresses and many usernames.
Email masking has become easier to use, and many people use `+addressing` to uniquely tie their email to the service for spam prevention / tracking, which would make stuffing harder.
In these cases, email would be much more unique and a better protection against stuffing. HOWEVER, it’s not obvious how Email verification protocol would work for these types of things.
