Did too many regulations doom implementation of the Affordable Care Act?

So argues economist Tyler Cowen:

For instance, the tangle known as government procurement has exacerbated problems with the Affordable Care Act’s health insurance exchanges. The required formal processes made it difficult to hire the best possible talent, led to nightmare organizational charts and resulted in blurred lines of accountability. It’s hard to turn on a dime and fix such problems overnight, no matter how pressing the need.
