The real trouble here is that the entities that need more addresses and the ones not supporting IPv6 aren't the same ones. In particular, a lot of large companies basically need one IPv4 address and they can NAT their whole organization behind it. Meanwhile ISPs and hosting providers need lots of IP addresses but can't switch entirely to IPv6 because their customers demand the ability to communicate with those companies that still only support IPv4.
But the government could probably fix it without even mandating anything. They should just... stop using IPv4. Does your company have to file tax forms with the IRS website? Only available via IPv6, so better get your network to support it.
