This is not about construction or the need for office space.
This is about guaranteeing insurance companies they will not have liabilities forced upon them from risks they did not accept, or collect premiums for.
To arbitrarily, & forcibly transfer risks on them; and prohibit all underwriting and compensation, would financially destroy them in short order.
As despicable as insurance companies are painted (and sometimes earned), we would not be able to do without them.
