If you don't buy insurance you'll have to pay an additional 1% for every year you're not covered... forever. Or something like that... They do a similar thing with medicare now...
I suspect dems left off a lot of stuff that would make people balk (even more than they are now) at the law... it'll all be added later. But until then your plan seem solid... Well unless you have a crisis - like a heart attack - and the hospital bill is close to $100,000 BEFORE you can get sighed up... I guess the old catastrophic insurance isn't available anymore...
Two points; one, hospitals are businesses, they will negotiate and will not deny treatment in life or death situations; Two, you can find policies that are for catastrophic events if you look for co-ops.
Co-ops have been exempted from obamacare.
