That's just plain BS. There are various networks with IPv6 nowadays
(have a look a the Google and apnic statistic pages) and various
IPv6-only nets already exist. If it breaks, people will notice it.

Because the amount of networks and machines massively increased during
that time.

Is there any good alternative - or even a concept?
I've never seen that and every time people come up with that, they
suggest "IPv4 with a larger address space", but don't understand that
such a thing cannot be implemented alongside with current IPv4, so no
migration plan at all.

Some small sites already did that: https://konecipv4.cz/en/

IIRC I've read that certain US government contracts require IPv6
compatibility.

Device which don't support it cannot be used.
