If you dont count the enormous expenses you might be right.Using an absolute like "ever" is misleading.
Fact is, the non-sick won't sign up until the last minute. This is exactly how it played out with RomneyCare, and how it will probably play out here.
If they don't need it, why will they sign up? It will be cheaper to pay the penalty and just use the ER for critical care.
Just like what happened under Romneycare.
RomneyCare was completely successful.
It was a pity Romney didn't run on it. He might have won.
