You don’t have a authority that decides what is useful and useless, what gets produced and what doesn’t.

Well sort of, the “authority” in the case of a truly free market is The Market (or The People, if you will.) If it sells it sells, if it doesn’t it doesn’t, The Market will decide.

That said, I agree with the rest of your statement and realize that you meant authority in a truer sense, and I in more of a metaphorical sense.
