I couldn't read every reply, and a lot are missing?
But to answer the title question~
We do have expectations, both for practical living and for how we treat each other. I am not going to get into a semantics debate over logical/natural/ etc. but, we are all to treat each other respectfully, and clean up after ourselves. If someone isn't living up to that, we figure out why and it gets resolved. Nobody is allowed to continue being disrespectful, but it's hard to summarize how we resolve it, since it's a very intuitive process.
I think for me, what feels wrong with an arbitrary punishment, is that it doesn't really address the actual situation.
I am all for resolving conflicts, and the expectation that everyone commit to it, but I do think it has to about the actual problem, dealt with in the present, and not some abstract set of rules and punishments that we hit each over the head with to express our unhappiness.
