The Future of Freedom Foundation had a civil liberties webinar recently. Ron Paul spoke about Property Ownership: The Ultimate Civil Liberty. From that page:
Dr. Paul explains how without property rights, all other rights are impossible. Starting with the ultimate property right, the rights to one’s own body, to the sanctity of contracts, to the right of the people “to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures,” property rights are the fount from which liberty flows.
