Why I can't delete me.com email address
why can't we delete a defunct old me.com email adress?

I am seeming to remember people saying Apple won't delete the address, but you'd have to ask Apple. Refer to this page for Apple Support features ➔ Contact - Official Apple Support
Select from the presented options until you find a solution for your issue, or see if there is a chat or phone call contact method offered lower on the page (you sometimes have to narrow down the options multiple times before this is shown). If you do not see your issue, keep experimenting with any series of selections until you reach one that offers a chat session or a telephone call and get the representative to redirect you.
This support article has various country telephone numbers for contacting Apple for support and service ➔ Contact Apple for support and service - Apple Support
If they will not delete it, set up mail filters to bock mail from that address. Set up rules to filter email in Mail on iCloud.com - Apple Support
