Normally I just ignore or take with grain salt the words that come out Gypsypooner mouth. But here I think time to comment a little.
This is big loss for hobbyists. Prices will not go down, they will go up. If there are fewer places to find to advertise, then the cost of advertise goes up. If the cost of advertise goes up, then the cost of whats being advertised goes up. Watch how fast those sites that allow buy ads mark up the price of ads, if they decide to stay in business.
If there is a lack of normal way to get references from well reviewed providers, then screening that happen before the days of references of known providers comes back. That means unless ( using me as an example ), if I don't know your references, your personal information is going to be necessary.
Finally if you raise the bar or level of what it takes to get in this business as independent, you will start to lower the number of providers that get in the biz and or stay in the biz. So for those providers who have no choice, you may have to dealing with their more knowledgable pimp in future. For those providers who cant figure it out, you will never get to deal with them as they will never get in or stay in.
I don't think the pass of the law will make any of the hobbyists any less horny, but makes finding suitable outlet for their needs harder to find.
