I found this server called Anarchy Network and it is a semi anarchy Minecraft world that feels really close to vanilla survival. It launched on October 11th 2024 and it is always online so you can hop on any time.
You can join on Java from version 1.7.2 all the way up to 1.21.10. They say it is best if you use 1.21.10 so stuff does not break. The world border is huge at two million blocks so there is a ton of room to explore and hide.
The rules are super light. Griefing and PvP are totally allowed and there are no map resets and no teleport commands and no pay to win at all. The only command you get that is not vanilla is spawn so you can get back to civilization if you go super far. You can also use the nether roof and phantoms are removed and only about half the players need to sleep to skip the night.
There are a few things that are not allowed. You cannot use exploits or lag machines or duping. You also cannot spam chat or use harassment or racial slurs. So the world is harsh but the basic behavior rules still exist.
If you like pure survival with chaos and big journeys and almost no rules this server fits that style a lot.
