Buckley and other wealthy conservatives were conservatives because it was the party of christianity, property, racism and classism. They were and remain revanchistes who use the language of libertarianism because they (and many of their followers) think it washes them of the ugly term bigot and racist since it appears to put the argument on a higher intellectual plane. Rand Paul (and others) explicitly argue that it is their libertarian principles, rather than their personal racist or sexist inclinations, that lead them to certain inescapable economic and political conclusions. But, of course, this is absurd
