I say we help push the demise of this arcane, obsolete agency. Utilize the Internet in every way possible; pay bills, electronic receipts, email, etc. then, write “Return to Sender” on every piece of junk mail you receive and put it back in your mail box.
As long as there is a need for certfied legal service with hard copy , and package service tthat will deliver to every US address plus APO/FPO, the USPS is not obsolete.
Heck, it’s one of the few things the national gov does that is actually contemplated by the Founders.
Your junk mail with” return to sender” will be chucked at the post office.
They do not return junk mail.
Junk mail is just that. Junk.
