Without having watched the video, but having an idea of what it's about given seeing a few places and creators I follow being sanctioned because the payment processors getting butthurt, I think it's worth mentioning crypto and direct competitors to the Visa and Mastercard mono(duo?)poly.

On crypto, if issue is that it burns too much energy, afaik generally new technologies are like that, improvements to consumption happening over time.

And about direct competitors, Russia made one from what I read, Brazil has Elo, and I think the EU was introducing their own recently. All 3 countries/country-like territories with their own problems, but I think it's a worth idea to copy and improve upon.

Also fomenting use of physical cash is a good idea too, me thinks.
