How does this would differ in terms of security compared to SSL/TLS?
The mail servers already use TLS.
If you don't control the private key, you don't control the readers, so IMO
it is not a point

Not only your problem, but we can not force anyone to use something - if
they want, they can. If they can not - they don't want. My personal
experience shows that people that really need it, also use it.

This is the point. When you really want to trust someone, you probably would
meet him/her and exchange keys face to face. Anything else is somehoe
dubious - but can also work if the one can confirm his/her key.
The point is that the verification can not be replaced by a machine or
application. You and only you are entitled to mark the key as trusted.

I include my signature on purpose now. It does not make any sense to encrypt
messages destined to the user group. But this is an example.

I still don't see any advantage, except that the server is secure and not
under US or EU law. Which means the probability to shut it down, or
confiscate it, like it happened in US is much lower.
