""The main reason is special interests who have an opportunity to lobby, be it concern groups that receive government funded, parents etc. who are naturally prone to bias from their own situation, or, more often, big businesses that benefit from the barriers to entry that are provided."
So, get rid of patents?"

"Healthcare can be sold across state lines. Health insurance cannot, which is different. If you are putting health insurance with healthcare...ok, but strange. Health insurance companies add costs to all medical procedures through overhead of profits and bureaucracy. Should we eliminate that?"
Carelessness in writing the post, but yes I would allow insurance to be sold across state lines.
"The drug companies better be doing the testing the FDA requires, or you are playing Russian Roulette with any drug you take. Who is to say what it does? Drug companies spend a lot on marketing and outreach to doctors to get people to use their stuff. That is nuts, if that is the path you are advocating. No testing, no barriers to entry, and lots of marketing?"
The FDA has strong incentives for being excessively cautious. An official can delay the release of a potentially life saving drug for decades with little criticism being lobbied, but if he makes a mistake on a drug which isn't safe, he will be fired and brought before the courts etc. A company, on the other hand, wants to maximise it's profits, which means being careful enough to reduce the risk of being sued for a dangerous drugs, but not by with-holding drugs for an excessively long time.
"That is great, in a system with perfect information, like a theoretical free market. In the real world, it works pretty poorly. How are you supposed to find out anything about the doctors or treatments? We can have a big Kudzu for doctors, I guess. Which would still be pretty poor information. You are kind of stuck in the theoretical. It is often hard to get good information on the differences between operating systems, and there aren't many of those."
You make a Nirvana fallacy: the legislators have imperfect information *and* counter-productive selfish motives too, so you cannot assume that the imperfect market will be bettered by the imperfect state intervention, and indeed the evidence I have seen points to the claim that it in fact doesn't.
Furthermore, the same claim can be made about cars- I know virtually nothing about what makes a good car good- but I can get advise from Which? etc. and buy one; even a bad choice will get me a reliable car.
