Why do you want a CEX and the government to have their hands in your transactipn? Does the recipient also have to deal with a CEX? If yes, that is another hurdle. And why do you keep referring to package theft when the cash is sent in an envelope and not in a package? Packages get stolen because they have stuff inside. Envelopes that look like random personal correspondence is much less attractive. If you have any stats about mail theft that is about envelopes, I'd like to see them, but stats about packages are something different imho. Fwiw, I live in an apartment, and any letters are delivered to my mailbox, which has a lock. There is not much likelihood of letters getting stolen after delivery. Packages that don't fit in the mailboxes are left on top of the mailbox, and those are much more exposed to getting stolen. Yeah I'm not speaking for other countries, not all of which have functioning payment systems. ETH (current version) does sound more efficient than BTC.
