> 1) The "market" (for what, you don't say) was created by government policy hundreds of years ago (but not thousands of yeas ago?)
By market, I'm referring to what we refer to as the market today, which is a relatively modern invention. Sure, for thousands of years there have been things called "markets," but they were far more limited in scope and their role in society was not nearly the same.
> 2) The market needs constant interference in order to not destroy itself (and again you seem to be referring to a great range of economic activity, perhaps all of it, but not all of it because you're also saying it would destroy "much else")
I mean, isn't this obvious? The market itself is not going to enforce contracts, it's not going prevent a wealthy person from paying for a private army and making his own rules, it's not going to do anything about monopolies and cartels (at least not on a reasonable timescale), it's not going to manage negative externalities, it's not going to address or mitigate socially destabilizing economic forces, etc.
The market is like a car: it some ways it may be a modern marvel, effortlessly regulating the timing of its complicated internal workings in a way no person could, but without a driver it will run out of gas and as happily drive into a wall than not.
