This seems like an impossible thing to regulate. What public good are you aiming to maximize? What has the market proven that it can't do without intervention?

This seems like an impossible thing to regulate. What public good are you aiming to maximize? What has the market proven that it can't do without intervention? How will you determine which market behaviours are the "bad" ones? In the case of gambling, I think the only protection the public needs is education ("the house always wins")--in the UK, at least, gambling regulation is usually in place to isolate gambling from other criminal activities e.g. money laundering, and to make sure the house isn't cheating, i.e. that it's a game of chance. Neither of those rationales seem to be necessary for skinner-box-like-games.
