These requirements can be perfectly well met with "renumbering when they
change provider", except for 4. - if a bit of planning is involved, and
not trying to stick to last century's technology.

Like: use mDNS or AD-provided DNS to find your printer and file server
(so the actual address it has today does not really matter).  Think twice
whether you really want to run your web site locally, instead of hosting
it somewhere which has more bandwidth, proper 7x24 operations, etc.

And indeed it would be nice if firewall vendors would hear the message
that being able to specify rules referencing a DHCPv6-PD-acquired prefix
is a needed thing...

But of course, you can provide all technology there is, and someone will
still want NAT.
