Libertarians are a never will be party precisely because they are disinclined to force their views upon others.
The points you object to are the logical conclusions of conservative principles. They may be unpleasant but nobody is compelled to go there; personal integrity is a choice, not a punishable compulsion.
Leftists, on the other hand, make those objectionable vices their starting principles (not marginal side effects) and leap off the cliff from there.
Libertarianism advances because of having a party, but they could never become big for obvious reason, the contradiction of trying to combine conservative economics with a left wing social agenda in the open where people can actually see it, does not win many voters.
The only way that libertarianism can prevail, is to either corrupt the democrat party on economics, or corrupt the GOP on social issues and Christianity and traditional Americanism.
