They certainly do answer some of the questions you explicitly spelled out. As for the rest:

1. I generally care if people are being pushed towards (under|in)-effective treatments. I want people to be guided towards the safest and most effective treatments for ethical reasons.

2. I worry that there are misaligned incentives between the drug consumers and the drug suppliers.

Maybe out of genuine concern for their fellow man, their suffering, and the possibility that parts of the medical establishment have perverse incentives. If you're arguing just to argue, you're an asshole. If you really feel that way then I feel sorry for you.
