Of course it is. It's a limiting doctrine that says "you may use the resources allocated to you within the property system, and no others".
This idea that property rights aren't a form of coercion is one of the most tiresome aspects of libertarian rhetoric.
Capitalism is a very effective economic system, and that efficiency often affords people more freedom than the alternatives, but it is still fundamentally a system of coercive constraints, as indeed any economic system must be.
