alt Hacker NewsIPv4 requires a DHCP server. It requires assigning a range of addresses that's usually fairly small, and requires manual configuration as soon as you need more than 254 devices on a network. The range must never conflict with any VPN you use. And there's more. Compare to IPv6: Nothing. All of these just go away.
And concerning the NAT: That's just another word for firewall, which you still have in your router, which still needs to forward packages, and still can decide to block some of them.

The dhcp server is in the router, just like you need a router for slaac.

Windows[0]: Static IP configuration is as simple as typing an IP address into the pretty dialog box. No DHCP required.
Linux[1]: # ip addr <ip4 address> <subnet mask> <device> will set a static IP address

Is 65,536 (172.16.0.0/16) or 16 million addresses (10.0.0.0/8) "fairly small"? Are DHCP servers unable to parse networks that "big"?

They most certainly do. But they're not "problems" with RFC1918 addressing and aren't "problems" at all with IPv4.
There are many issues with IPv4 and the sooner it dies, the better. But the ones you mention aren't issues at all.
If you're going to dunk on IPv4, then dunk on it for the actual reasons it needs to go, not made up "problems."
