Yeah this is exactly what free market lunatics on the right don’t understand. Monopoly isn’t a free market. Free markets simply cannot exist without regulation to prevent unfair business practices.
Also any reasonable economist can tell you that the free market does not solve issues like the tragedy of the commons, because negative externalities are not factored in. It is also the government’s job to ‘internalize’ externalities so companies actually see the costs of, for example, polluting our air and water.
TLDR: free market != unregulated market
The point is the requirements have been tailored so that they aren’t just buying bibles for schools (already bad), but their only option meeting the requirements will be the Trump one.
