Neither one is a carefully defined political philosophy that stands consistently on one side on every issue. I like Mr. Brownee and I think the public interest is well served when he has a voice in national debates, but not only is this a pointless challenge, it's also a disappointing one. I could probably also come up with a bunch of one-liners of my own. But ultimately none of these would be to Mr. Brownee's satisfaction, or mine. I can name all sorts of ideologies that are more consistent than conservatism, Marxism heading the list.
Consistency has zero moral content.
It is neither good nor evil nor anything in-between. But it is useful. Hence, the chief benefit of having libertarians in the conservative movement, even when their advice goes unheeded, is that they keep everyone on their toes. Admittedly, conservatism is not always and everywhere on the same side of every issue, like Mr. Brownee's version of libertarianism. Well and good.
