There are, of course, many libertarians who are believers. Buckley would be a notable example. If not a majority, then certainly a great many other libertarians are non-believers. As such, they hold that "man is the measure," just as the left does. But this is the crucial error of the left, failing to acknowledge our historically obvious fallibility, our thoroughly ingrained sinfulness, our need to humble ourselves before our Creator and accept His guidance. Engineering alone won't suffice, and, for all their reverence for the founding documents, this is where non-believing libertarians go astray.

Your points about the existence and failings of Godless libertarians is certainly worth exploration. But a Godless libertarian has no problem with having uncoerced prayer in schools, Christmas displays, or free exercise of religion. Consequently, they are far less a threat than liberals.
