Those proponents of liberty who advocate the voucher system fail to recognize that, in so doing, they are giving an implicit endorsement to a principle that they profess to oppose. The fundamental premise of the voucher plan is identical to that underlying the present system of state education. The coercive power of the state (which in the final analysis means the threat or use of the gun) will still be used to seize the property of private individuals in the name of an undefinable public good.

— Robert Patton, The Freeman (April 1971)
