The aspect of "my house = my rules" works quite well in Fediverse. You create an instance with a bunch of like-minded people and you federate with others. If another instance doesn't like you they defederate you. So you can have your rules and still be a part of a larger structure. But then: mega instances 🙃
Free speech is a bit of an impossible concept for me so I'll leave it. But generally yeah there are various channels of expressing oneself
