Depression and dread is coming through me. All the repressed memories are flowing back up.

Might as well say the people who read your books aren’t allowed to teach the concepts or theories. Completely asinine argument. If you don’t want the knowledge to proliferate, then don’t publish. They’re not copying and redistributing.
Meanwhile, jurisdictions outside of us copyright protection will leapfrog us because we can’t get out of our own way.

If you know the steps -- install software, download root hints file, glance at default config (probably no changes needed), set packet filter rules, start daemon, update DHCP config -- you can be up and running in less than 10 minutes.
If it's your first time, but all of those steps are conceptually clear, I'd allot an hour or so.
I'd recommend Unbound[0] or Knot Resolver[1]. Either will give you fast local caching and private DNS history, with zero maintenance requirements. I literally have not touched my (Unbound) config in ten years.
Though, now that I think about it, there have probably been root hints[2] updates that I should download. (30 sec later: Done!)
