You've likely paid at least $18k if not more like $25k for that insurance in the form of wage income moved to benefit income. The government's tax and regulatory environment post WWII just ensures that unless you choose to take it as 1099 income, your potential 1099 income gets reflected in reduced W2 wages that are paid out in benefits.

You might claim that if your employer didn't offer that benefit they'd just pay nothing, but required health benefits function much as payroll taxes which economists have showed are largely reflected in the form of reduced incomes. That is, you are paying it ~all one way or another.
