I don't like paltry sums like this. $300 is a significant financial impact to someone who's barely making ends meet, and absolutely nothing at all to a billionaire. "If the penalty for a crime is a fine, then that law only exists for the poor."
Make it a tiny % of net worth, with a modest minimum and watch EVERYONE obey. Or at least something meaningful to everyone, or don't make it a fine. Use some other carrot or stick.
