P2p is not an app, it's a technique for implementing an app. There are
few apps which require p2p and can't be trivially redesigned not to.
If you'll pardon me saying so (and even if you won't) those few boil
down to bit torrent and its cousins: used almost exclusively for
unlawful activities by cheapskates whose wallets are too few and too
small to drive the system.

I wouldn't put it that way but yeah, that's the gist of it. There's an
unambiguous and very strong capitalist profit incentive to make your
new technology work with IPv4 and NAT. The comparable profit incentive
to make it work with IPv6 is weak almost to the point of
non-existence. And there is a severe shortage of networking staff
capable of implementing technologies that are different than what an
organization has implemented before. That market push facilitates
deployment of CGNs while sucking manpower away from IPv6.
