I found a Minecraft anarchy server called MinecraftOffline that runs on 1.21.11 and it is all about doing what you want.
The world is eternal and they say it never resets so your builds and mistakes stay forever. Gameplay is enhanced with bespoke plugins so it is not just plain vanilla.
It is hosted in Finland which should feel good for European players and it is built on reliable hardware so it should stay stable when you are trying to survive the chaos.
Toms3 is a cracked anarchy server that came back with a brand new world after being gone for years. It is inspired by 2b2t and Hisparquia and it is meant to be a small fresh option.
It is full anarchy with no admins and no rules. There are no bans no filters and no shadowbans so people can play however they want.
It tries to stay near vanilla with only small changes to keep it stable. There is no /tpa and no /home and the chat is like 2b2t with greentext plus /w /r and /ignore.
There is a separate authentication server and premium players skip the auth part. The anti cheat is relaxed so stuff like ElytraFly AntiKnockback Velocity and NoFall should work but flight is blocked.
The server has two dupes listed which are an item frame dupe that is nerfed and a donkey dupe on 1.15.2. Printers work with Litematica and Air Place works too. Crystal pvp is changed since anchors and offhand crystals are heavily penalized.
They say it is built for long term and if it ever shuts down they will release a full world download. The server has had hundreds of unique joins and a small daily playerbase.
This server is straight up vanilla anarchy on version 1.3.2. There are no rules and nothing is patched so it feels like the real deal.
It only uses official jar files. The server can update every week and players vote on it.
They are going through every official server version including snapshots and even april fools versions so it can get really weird over time.
Anarchy Network is a semi anarchy survival server that tries to feel like real Vanilla Minecraft with only a few changes. It started on October 11th 2024 and it is hosted in New York City in the USA.
You can play 24 7 and it lets you join on Java versions from 1.7.2 to 1.21.11. It recommends 1.21.10 so you do not run into problems.
The world is huge with a 2 million block border and there are no map resets. There is no pay to win and there is no teleporting. Griefing and PvP are allowed so you have to watch your back.
The only command you get is spawn so people far away can get back to civilization. Nether roof is allowed phantoms are removed and only half the players need to sleep to skip the night.
They do not allow exploits lag machines duping spam or harassment and racial slurs in chat.
I found MinecraftOffline and it is a lifesteal anarchy server where fights matter a lot. If you die you lose hearts so people play careful or they go full chaos.
It runs on version 1.21.11 and it has a zero reset policy so your progress stays. The server is hosted in Finland so it should feel good for players in Europe.
It also has custom plugins so it is not just plain vanilla. This one feels like a place for raiding and PvP and messy survival all the time.

The server stays online all the time and it lets you join on Java versions from 1.7.2 up to 1.21.11. They say 1.21.10 is the best one to use so you do not run into problems.
The world is huge with a 2 million block border and there are no map resets. There is no pay to win and griefing and PvP are allowed. There is no teleporting except for a spawn command so players far away can get back near other people.

I found a server called MinecraftOffline and it is all about lifesteal and anarchy. You can fight people and losing feels brutal since the gameplay is built around hearts getting taken.
It runs on version 1.21.11 and it has a zero reset policy so the world is meant to last. The server is hosted in Finland so it is aimed at good connections for Europe.
It also says it uses custom plugins and it lists strong hardware so it is trying to stay stable even when things get chaotic.
CorruptMC is a semi anarchy survival server that feels like chaos but still has a few rules so it stays playable. It is not one of those servers where everything is protected and nothing can happen.
There are no land claims so you actually have to defend your base or accept that it might get raided. Players make their own fights and team ups and the staff is friendly but they still want the server to stay wild.
It runs on 1.21.11 and it supports Java and Bedrock together using crossplay. The host is in the US but anyone can join. Events are planned to start soon and they are run by the community manager.
I found a hardcore survival server where you only get one life and that is it. If you die you are done so everything feels super serious.
The world is huge so you can run far and try to hide your base. The Overworld is 300000 by 300000 and The End is 50000 by 50000 so there is a lot of space but you still might run into people.
PvP is meant to feel more like old school fights with swords and bows. End crystals and respawn anchors are not allowed for PvP.
Griefing killing and scamming are allowed so you really cannot trust anyone. Cheating hacking and exploits are not allowed so if you win you actually earned it.
One Anarchy is an anarchy server with no rules at all.
It is the kind of place where players can do whatever they want and the world can get really chaotic.
If you like pure anarchy gameplay then this server is basically built for that.
