That's a fun "modern" twisted definition intentionally skewed from how Adam Smith, among others, would define "free market":

> For classical economists such as Adam Smith, the term free market refers to a market free from all forms of economic privilege, monopolies and artificial scarcities.

Employer-defined healthcare creates troughs of economic privilege, builds monopolies with respect to laborers, and enforces artificial scarcity in the supply of labor. It removes liquidity in the labor market if laborers aren't free to bid their labor to the highest bidder at any time simply because they can't risk their own health care. It's not a "free market" determined "solely" by supply and demand when the supply is artificially limited by the rent seeking inherent to employer-defined healthcare, no matter whether or not you think the solution is fairer labor regulations or how much you claim to hate government oversight. That's a market failure.
