Libertarians do oppose conservatives on issues, that is why the article is talking about liberal millenials being libertarian, and not conservative and why libertarians don’t merely call themselves conservatives.
You miss the point.
Just like Rand Paul
Rand Paul does not speak for all libertarians.
You don’t seem to speak for anyone or anything, you keep arguing for the sake of arguing, but there is no making out what you are arguing for.
And Rand Paul is currently the most prominent libertarian politician and the darling of the libertarians.
