Hi,
I read your poste yesterday.
You can see my opinion in comments under juliakponsford's post.

I like your idea about state laws as long as they are not abusing Hive.
If some art contest or community sets up such rules, then it's all good.
To avoid confusing between understanding what rules what communities/posts have, the posting user could give short and well visible rule intro in the post, Hivewatchers can keep up to date about different "state rules" specific to different posts.
