Say what? My email addresses are linked to my identity because they are my email addresses. Most of them even have my name on them. Sure, I have several of them, and one of them disappeared when I graduated from college, so the mapping isn't perfect -- but they are nevertheless mine.
The main exceptions to this are:
1. People who share an email address for convenience, like my grandparents.
2. Group-facade email addresses, like support@whatever.com, which may be routed to several people.
3. Email addresses that don't belong to anyone, like "noreply@whatever.com", or "autogenerated-4b243efa37e5b013a1d90b694c3bcaa3@hell.com"
