I'm thinking maybe everyone should relax and not panic and see how it plays out.
No one needs to quit pooning, working, or to start making and selling porn or trinkets like gypsy's either. You can see established providers, touring or otherwise. Who knows? It may good for getting rid of rip off and scam artists. I don't travel very much anymore but I don't see too many issues with that either. Equal risk probably?
This might be a non event like Y2K
We'll adjust. Change our ads, methods of advertising, talking etc. It's hard to stop something like this completely. Most LE agencies will probably use this law for organized human trafficking and underage shit. If they were smart, and I said IF.
