You speak of modern Libertarians, not of Libertarian originalists who believed that the state should be kept to the very minimum to provide strictly proper constitutional services.
To conflate the two is the equivalent of putting RINOs and actual Republicans in the same box. Just not fair.
The only places that Libertarians differ with actual Republicans is as it pertains to personal behaviors and the proper size/scope of those constitutional services of government.

Wrong. Open borders, abortion on demand, prostitution by both sexes of any age - at any time, legal drugs of all kinds, none of these are congruent with actual GOP platforms or policies.
