I'm against third parties buying insurance. It is just an artifact of the tax code and wage and price controls during WWII. Individuals and families, and self-defined groups ought to be able to buy insurance for themselves without the tax penalties of the current system.
I agree. The whole system is a mess.
I think that until we find a way to fix it, tinkering at the edges to cut chunks of the population out doesn't really accomplish anything positive. It causes some people to cling to inappropriate jobs they'd otherwise leave, it forces others onto the state, and in the end we all pay more and things get worse.
