Gee, lets do the same with everything. No government regulation for anything. After all, you can choose what is an acceptable risk. So what if you didn't know that Uber drivers aren't properly insured? Why not unregulated food manufacturers who can sell you bacteria-laced meat? Why not unregulated cars that are unsafe at any speed?
Yes, food & automobile manufacturers have a strong incentive to kill their customers. It's good for long-term profits.
Why not unregulated medicines that are as likely to kill as to cure?
Vioxx was FDA approved, and killed 60,000 people. Meanwhile, effective drugs are unnecessarily kept off of the market by the FDA, like Provenge. And those are only 2 examples.
And unregulated banks that can take your money and run?
Or the regulated banks that can do that legally.
Hey, go all the way - allow the issuing of unregulated currencies
Why not? The Fed has done such a bang-up job.
the use of non-credentialed teachers from the local state pen, and everything else?
Yes, credentialed pedophiles that the teachers' union support are much better.
The fact is that regulations are supposed to ensure that the consumer doesn't have to spend hours investigation who is and who isn't competent themselves, as well as provide a feedback mechanism when the regulations are broken.
There are a boatload of ways to find out about what products are good and which businesses provide competent employees, such as the Better Business Bureau, Consumer Reports, Underwriters Laboratory, as well as review web sites, etc. I'm not saying unregulated markets would be perfect, but I believe that they would by and large be a better solution than the current regulatory morass we have in this country.
