IPv6 is semi-permanent till the provider would not change the prefix or the user would not change the provider.
In this period, it is possible to use this IP address as static (if you want, because some registry or DNS is better).

NPT is completely orthogonal to this. It does not improve or create any additional problem for this situation.
IPv6 is just semi-permanent by itself.

So why do you bother with IPv6? You must have been perfectly happy with IPv4 if you think there is nothing wrong with forcing end user devices to be clients only.

That ship has sailed long ago.

All this stuff works by registering some sort of identity at a central
server, and that server will relay the session setup (and knows the
member IPs).

Nobody calls "an IP address".  So you need the registration/mapping service
anyway.

(And to find the central server, a magic service called "DNS" was invented)
