IF there is no law then how do you fix the problems? I remember years back when a law had to be created so money exchange shops had to display the commission with big fonts under the place they display the prices. The law fixes the issue people had, fixing it with free market and wishful thinking would have cost much more. I think you can find some good enough rules on how things should be without forcing the use of the exact font family and color.
