Intellectual property laws are incompatible with Libertarianism.
Lemme rephrase. Do you have anything against the concept of intellectual property?
IP can more easily be debunked from this prospective:
An non-violent act (copying information), needs a violent act (the enforcement of IP rights) to be stopped.
That "debunk" is redundant. You assume intellect cannot be a property so that to copy without consent does not consist in theft. To debunk it, you need to start from the assumption that it consist in property and prove that at some point it contradicts itself or makes no sense. In this case your attempt fails, since you have to assume it stands as a property, in which case the copy is theft, which is aggression.
