Without the sate and its laws and enforcement of property rights you will have a very fragile and vulnerable economy. The nation state and its ability to enforce property rights is a significant contributor to the wealth of nations.

There has never been a sustained and prosperous economy without a government to oversee and protect its resources, property rights, rule of law, trade routes and markets.

If someone develops a new idea, medicine or process, and that idea, medicine or process has value then it is adding value to the economy. To fail to reward the originator of that idea, medicine or process is to fail to reward technological and creative value development. Such a failure is to disincentivize and stifle development and creative work in your economy. Only Libertarians could be so deluded as to think that is a good outcome.
