The copyright monopoly is a limitation of property rights.

Misconception number five goes back to the original point of the copyright monopoly being described as “property”. After point four, we observe that the copyright monopoly is a limitation of property rights. This is a point important enough in itself to list as a fifth misconception: property rights and the copyright monopoly don’t and can’t coexist peacefully. The copyright monopoly actively limits property rights.

Thus, if you take your stance in the safeguarding and upholding of property rights, you cannot defend the copyright monopoly and its limitation of said property rights. That’s like defending death penalty for murder with the justification that all life is sacred. There may be other justifications – but that particular piece of logic just doesn’t connect.
