This video heavily promotes Monero, but as part of a complete package for liberty.

Libertarians promote political freedom, but often ignore technology freedom. For example, the main party website LP.org makes 3rd party JavaScript calls to Google and Facebook, visible with the browser extension uBlock Origin. This JavaScript allows these Big Tech firms to do surveillance on behalf of the government and these are the same organizations that suppress pro-freedom speech.

Most Libertarian groups such as Mises or Cato are reliant on Democrat-controlled big tech platforms to spread their message and do not teach fundamental decentralized tech infrastructure for resilience against oppression.

This video goes over an introduction to Digital Freedom for Libertarians including:

1. Operating systems on the phone and PC
2. Monero gift cards & debit cards
3. Decentralized Instant messaging
4. Decentralized Email
