I found a semi anarchy survival server that tries to keep things feeling like real Vanilla Minecraft. It has very few changes and it is meant to be a long term world.
The server runs all the time and it supports Java versions from 1.7.2 up to 1.21.11. They recommend 1.21.10 so you do not run into weird issues.
The world border is huge at 2 million blocks so there is a lot of room to travel and build. There are no map resets and there is no pay to win. PvP and griefing are allowed and there is no teleporting. The only command they allow is spawn so people far out are not stuck alone.
You can use the nether roof here. Phantoms are removed and only half the players need to sleep to skip the night. They do not allow exploits or duping or lag machines or spam. Chat harassment and racial slurs are also not allowed.
