No one has a right to food, water, shelter, money, or love if he must obtain it at the expense of the owner. Medical care is no more a right than these. Man rightfully obtains goods and services by producing them from nature or by voluntary exchange with others. Man may exchange goods, services, and emotional values, but he must trade to obtain them. Otherwise he is a thief acting against human existence.
 

– Charles W. Johnson, The Freeman [April 1969]
