I found a 2b2t style anarchy server called 2 Paws 1 Job and it is all about true no rules survival.
It runs on 1.21.11 and it is on dedicated hardware. They say it is built to handle 500 plus players with no lag.
There are no resets ever so whatever happens stays. Dupes are allowed griefing is encouraged and pvp is always on.
It tries to feel near vanilla with custom plugins and there is no pay to win and no protected spawn. You can join instantly with no whitelist and it supports Java Bedrock MCPE and cracked clients too.

I found FreeLife SMP S3 and it is a vanilla Java SMP. It is semi anarchy so you get a lot of freedom but there are still some rules and they are posted in the Discord.
The server has voice chat installed and it can hold up to 200 players. It is averaging around 5 players right now and they are trying to get more people to join.
There is a rule about the mace because the owner dislikes it. The mace will be craft banned for three days so people have a fair chance to get going. The server opens at 3:30pm EST and the owner is trying to make videos on the server too.GG.MINEWIND.NET New Server IP
