Eternal vigilance is the price to be paid for a well functioning free market. The same Principle of “democracy is the least bad system of governance” is applicable to free markets as well. I am not in favour of untrammelled free markets which could lead to monopolies. In fact it means that equal access is not being provided fairly and is actually a breakdown of free market principles
Similarly, not pricing common resources (such as clean air, water etc ) means again a breakdown of the free market principle of fair pricing of inputs.
In our gear example , free markets means that anyone is free to buy any gear at the right price and connect it to any black gear in the economic machine.
