If you want to establish *clear consequences* for breaking the rules then how about we add to each edit window a statement saying "By saving this page you agree to the rules and conditions of using this website" (rules and conditions would link to our policy page). Of course we would have to redo the policy page so that only real policies are on it. The policies listed IMO should be; NPOV, no copyright violations, 'we are an encyclopedia' and yes Wikipetiquette.
I like this idea, although rather than change the main policy page, we should have one specific [[Wikipedia:Absolute policies]] page, and link to that. This page should be locked. (If we're really paranoid, then we could link to a specific spot in the page's history.)
We can then discuss what should be on that page, which should always be kept very short. I agree with the first 2 of your 4 suggestions, and I await others' opinions.
