Seriously Prateek, I wonder who you read around here.
Some folks from here who would do a good job are Stephen, Solid Choke, Jon Irenicus, Angurse, Jack Cuyler, Physiocrat, AJ, the list is long.
I’d pick voluntarists and anarchists.
Doug Casey, Stefan Molyneux, Marc Stevens and maybe John Harris. None of them are public intellectuals, none of them are Hayekians, all of them live and die in the private sector.
It’s hard for me to think of anyone better than Hulsmann, if we include people skills. He can rise above the situation and not allow himself to get upset, while appealing to the audience (sense of humor) and have great enthusiasm, AND understand the material extremely well.
As a non libertarian, the five libertarians I find most convincing are Cowen, Tabarrok, Friedman Sr. (dead) and I can’t think of any others off the top of my head so I guess Cowen twice more.
