As for the video itself that question was answered a while ago, and the guy in the video has fried a fuse. This was my answer:
Nah, the Amero idea originated in Canada from a guy called Herbert Grubel or Gruber from the Fraser institute in 1999 but never picked up. Mexicans discussed it in their cabinet as a hypothetical option.
It was theorized that with the Euro coming up, and Nafta being relatively new the Amero would be a natural extension.
He’s talking a lot about things he doesn’t know squat about, e.g. a “Force Majeure” is by definition an act of god or nature. Say, fire, storms etc. You can’t declare “Force Majeure” on your currency lol.
Further, he says buy French Francs not Euro, idiot, the Euro replaced French Francs as France and Germany were the driving force behind the Euro. This guy is a nutjob.
I’d say paranoid delusional that guy, typical conspiracy theorist.
Remains to amend that only the UK have actually retained the Pound, as far as I know they are the only European country that retained dual currency standard (Ireland too maybe?).
As for feasibility, across North America it would be virtually impossible to merge, as the prerequisite for a unified currency is complete and entire standardization of the involved economies. Canada, US and Mexico are simply not compatible. The Euro was in the making for the better part of 20 years. That’s the time it took to even find common standards.
