> I heard a few years back that a US health insurance startup had to provide on the order of 6000 pages of documentation to be approved. No wonder that there hadn't been another provider for twenty years or so.

I think the difficulty involved in spinning up an insurance company probably has literally nothing to do with those 6000 pages of documentation, but if I suspected otherwise, it would seem like what is actually on those pages is a lot more relevant than how many of them there are.
