I found The Frail Snail SMP and it feels like pure chaos in the best way.
It is basically an anarchy SMP with almost no rules so people can do whatever.
It also has guns and it has Create so you can mess around with crazy fights and builds at the same time.

GG.MINEWIND.NET New Server IPCracked No Cheats Anarchy SMP
I found a cracked anarchy SMP where you can do basically anything and the world is meant to be chaotic.
They still have some rules though like no cheats or exploits. They also do not allow rape jokes or extreme racism.
The server hosts weekly events. It supports Java and Bedrock on version 1.21.11 and it says support goes until 26.0.GG.MINEWIND.NET New Server IPNightClub SMP 9PM EST Semi Anarchy
I found a new survival server called NightClub SMP and it is semi anarchy so the players kind of run the whole place.
It is not super strict and it feels like a sandbox where alliances betrayals traps raids weird politics and random wars can happen if the right people show up.
Stealing and raiding are allowed but only if the other player is online and knows it is happening. Cheating is not allowed and neither are lag machines or server breaking stuff.
You have to join the Discord to play and the server IP gets posted there when it opens. There is also a daily playtime system and you can earn bonus time.GG.MINEWIND.NET New Server IPEmperium SMP Semi Anarchy Beta
Emperium SMP is a new survival server that is still in beta right now. It is meant to be a semi anarchy style server with some plugins.
At the moment the only thing open is the anarchy server. The owners say they are working a lot to add more game modes later.
People of all ages can join here. There is freedom to play how you want but obvious bully behavior is not allowed. So you can still have chaos but without people being toxic on purpose.
If you want a fresh server that is just starting and you like a semi anarchy style this is the kind of place you might want to try.GG.MINEWIND.NET New Server IP
