Many years old routers had a single external ipv4 and behind the NAT each computer got an internal ipv4 as a way to never end up exhausting the pool of IPs that each ISP has. But it’s been a long while since it has changed:

Most of the home networks I use are still behind a NAT use a single ipv6 to interface the world and within the network each computer has an internally assigned ipv4 just in case some operating system may not be compatible with ipv4.

Still are many old routers using ipv4 only out there as not many people care to renew their hardware as long as their WhatsApp and Netflix works.

Well, if governments really care about IPv6 (and the previous campaigns to push it were not just about "look how progressive we are"), they'll do something similar to what they've done with digital TV broadcasting :

they would first ban the selling of new devices not compatible with IPv6, then forbid ISPs to advertise IPv4-only connections as "Internet", then ban the selling of new IPv4-compatible devices.

(In a few years we're going to reach anyway the point when IPv6-only connections (mostly in Asia) outnumber IPv4-only devices (mostly in Africa, which sucks because they're the least able to afford an upgrade, but then being forced behind CGNAT sucks too).)
