"Other than that, Mrs. Lincoln, how was the play?"
The protection of property rights is the fundamental bedrock of all institutions. To dismiss it, even by implication, bespeaks profound ignorance of the basis for civilized life.
My assertion had little to do with "property rights" by which people usually mean the "right" to acquire, dispose of or exclude others from using or abusing one's property whether real, personal, evidences of debt or things-in-action. Libertarians and Marxists simply differ as to who will hold title.
Libertarians and their use of the term property are usually ignorant and/or superficial. For example, the usual Libertarian rejection of pure food and drug laws and the Libertarian profession of allowing the "market" to determine what to do with someone selling a toxic substance added to food. Ridiculous!
No sane man has ever denied that property use requires regulation.
