What happens when insurers cant guarantee the viability of the infrastructure projects and the long term assets they invest in. I haven't seen any projects like that being done in an efficient, timely and fiscally prudent manner over the last two decades. There is a reason they are high risk. I'd expect and explosion in costs and time caused by regulations, planning and court cases.
So either:
Layoffs and bust companies,
Money printing bailouts paid for by Joe Blogs
or
Massive insurance premium increases for Joe Blogs to cover the losses.
All bad for the country in the current climate.
