Will Obamacare actually implode, probably not. Although, according to CNN:
For 2016, the benchmark plan's premium rose only 7.2%, on average, for the states that use healthcare.gov. (Looking only at states on the federal exchange, premiums are rising 25% for 2017.)
The average premium increase masks wide variation among the states. In Arizona, the benchmark plan's average premium will increase 116% in 2017. Arizona had the lowest rates of any state this year, said Kathryn Martin, an acting assistant secretary at the U.S. Department of Health & Human Services.
So, if you want your Obamacare, you can keep your Obamacare....at a much higher price. Oh no, your insurance carrier fled the state....guess you're out of luck.
