Are "free markets" possible without government?
No. For we need the protection of collective freedom to prevent individual freedom from running amok.
But governance can take many forms and the governments by which we deploy governance today are in flagrant violation of the very principles that secure freedom. Government too needs to adhere to the principles of freedom to support the best proxy of freedom we aim to achieve.
Bottom line is, we must first define and free freedom before we can reap the benefits of its outcome.
