Isn't Doug Casey an advisor to this guy?
Discussion
Doug Casey lives in Argentina and talked briefly about Milei in his recent talk with Saifedean. The tldr is he likes him but isn't involved in his campaign. I highly recommend the episode:
The Bitcoin Standard Podcast: 180. Applied Anarcho-Capitalism with Doug Casey
Episode webpage: https://saifedean.com/podcast/

Yeah it was a good one. That's where I got the reference.
