You are completely missing my point. What you view as morally inapprpriate behavior (multi-house owning, property flipping), others might view as acceptable practices of modern capitalism. You CANNOT saddle the playerbase with an arbitrary moral code, whether you like it or not.
Square can set "rules", or "terms", with clear consequences for those who flout or break them, but any "honor code" invented by the playerbase is total rubbish and holds no real bearing outside of potential social repercussions (blacklisting "early hunt pullers", run sellers, or other practitioners of concepts you don't personally agree with).
