There are certainly aspects of our market economy that are emergent. Trade is as old as humanity itself, but not all aspects of the economy are so old, nor as immutable.
The modern corporation, for example, is a relatively new invention. Depending on your definition, anywhere between a few centuries and a few decades old. Compared to the time scale on which human evolution has taken place, that's practically nothing. In those decades or centuries, we and our ancestors have chosen particular shapes for our economy. Not all of those choices are final.
Whether the choices that influenced this particular example can be changed, I don't know, nor do I feel qualified to hazard a guess. However, I stand by my original point: it makes no sense to refuse to consider how we might improve the system.
