Since libertarians and conservatives agree on economics, that would be a strange thing for anyone to say.
LOL, only you could get confused by that simple and accurate post.
Do you believe in private property but not private wives?
That's the blunt way that Christians in the 1800s responded to socialists and Communists who wanted to introduce not only community of goods but also free love.
By the time of Stalin, Russian Communists had figured out that a Communist view of loose morals didn't work in practice and started re-instituting something comparable to older Christian views of family life. However, we still today see Cuban Communists taking children away from their families to be raised in collective schools.
The simple fact of the matter is that Judeo-Christian views not only of work ethics but also of personal morality are intimately linked to the success of Western civilization.
Libertarianism seeks to have the economic principles of Judeo-Christian culture without the moral principles.
I do not believe that is possible over the long term. But there's a certain wing of the Republican Party that seems bound and determined to try that experiment and see if it works.
