It is the "free" market.

In air quotes to emphasize that it is not free.

The market – businesses – have become adjuncts of the government by dint of having accepted that they must obtain permission from the government in order to be in business. This, in turn, gives government control over the business – which now extends to the demand that businesses enforce "mandates" that are not even laws such as the wearing of the Holy Rag within their establishments.

If they fail to enforce the "mandates" – irrespective of their dubious legality – they are threatened with extortionate fines and the rescinding of the government's permission to be in business.

And so they enforce the "mandates."

This follows naturally – inevitably – from the precedent set once-upon-a-time that it is the job of businesses to collect taxes on behalf of the government. Which they now do unconsciously, as a matter of routine.
