The individual and employer mandates are huge cash cows for the industry. I imagine every business in this country would clamor for a Federal law that required people and employers to buy the products they sell.
The downside is that insurers pretty much have to insure anyone who comes to the door. This is like requiring an auto insurance company to offer an "affordable" policy to someone with four DUI convictions and nine license suspensions on his record.
Some states do have that. It is called Assigned Risk.
