The auto insurnace thing aint even close the the same. You don't have to buy auto insurance hundreds of millions of people don't - O-car everyone is forced to buy insurance, young and old alike, car or no car; and if you don't you can get one of them "I will not raise taxes on the middle class" taxes. Auto insurance you can pick what suits you, higher deductible, PL-PD only, $1M of coverage, $1K of coverage, etc., etc. etc. O-care you have 3 choices, all of them expensive (unless of course you get one of them take from someone else subsidies).
