Politically, we have little choice but to work with reform-minded prohibitionists in advocating and designing compromise policies that remove the worst aspects of drug prohibition. And intellectually, I find it difficult to imagine a libertarian approach to drug control surviving the inevitable pressures to protect children and mentally disabled adults from unrestricted drug availability. Let me take this opportunity to point out one other area of dispute between libertarians and those, such as myself, who are more civil libertarian in our preferences. I believe strongly in a right of privacy and bodily integrity and favor laws that would severely restrict the power of employers, both private and government, to test their employees' urine, blood, hair, and skin for the presence of drugs. There is, I believe, no way of finessing this conflict of fundamental rights.
Libertarians have no choice but to choose which rights they want government to elevate over others.
