The very smart scholars over at Crooked Timber (here) have a fascinating series of posts on the myopia/ignorance of libertarians who claim the 1880s as a "golden age" of individual liberty in the US. Indeed, it was a golden age, but only if you were white, adult, and male. Otherwise, not so much.
Libertarians who want to be taken seriously, should be careful about comparing epochs. Less government regulation of business or land use and lower taxes do not necessarily equate to more freedom for everyone.
