That's sort of the history of the law. You outlaw crime (new types of crime are variations of fraud, deceit, etc) and then people "innovate" their methods to get around that and you outlaw that too. Hopefully suppressing them more than they "innovate". But we don't have to just hope, we historically suppressed these new crimes when it became a big problem.

You dont just give up and let them create and do new types of (yet to be classified) crime just because they will always predictably want to do it anyway.
