I don't get the argument you are making about free-riding, Fate. If there is someone in their 20s who has a decent income but doesn't want to make spend money on buying insurance they pay this tax (fine) because that makes economic sense for them. However, if that person gets seriously ill and they have no insurance they will significantly free-ride on the system; however, at least they will have remied the free-riding to some extent by paying the penalty (tax)
If you took 100 people in their 20s who did not buy the insurance and paid the tax-, then the tax paid by most of the 100 could come close to ultimately paying for the medical treatment of the few who would require extensive treatment. I think you are trying to make the argument that is just a way to have tax increases and it is nothing to do with the free-rider problem. But I think the proof that it was designed as a tax increase is pretty thin. The design is (1) have healthy people attractive to insurance companies get into the system, and (2) to a lesser extent cure the free-rider problem. Would the Administration be happy if everyone bought insurance? I think the answer is yes if you have some arguments to the contrary I would like to see them. Otherwise, if the preference would be to have everyone buy insurance then it is not a tax increase (it is simply a penalty and not designed to increase tax revenue)
