Adopting a Bitcoin standard bc it's what he personally wants introduces coercion into the equation. The Argentinian people will speak for what they want to use, ultimately, and Bitcoin is inevitable.

In the meantime, we live in a fiat world and Argentina will have to operate as such, while (hopefully) building out the parallel infrastructure in preparation for the death of the dollar.
