Keep in mind, Schumpeter was not a libertarian in the vein of the Austrian school of Mises, Hayek or Rothbard, which seems to underpin modern libertarian thought such as Thiel's.

He was more properly a conservative or classical liberal in the tradition of J.S. Mill: supportive of business and the free market, but supportive of "intelligent monopolies" themselves at times, like the early Bell Telephone system... He also met his intellectual opponents (eg. Marxists) with respect (a rare thing these days), and didn't place market economics at the centre of all human activity as is common with libertarian thought which reduces all acts to market transaction.
