I’m with you on the answer being to root out corruption and for the country to get its affairs in order. As for establishing a new banking system, isn’t that exactly what they are doing - albeit using Bitcoin and Lightning instead of fiat. El Salvador is a poor country and 70% of it’s citizens lack a bank account (but most have a phone.) The reason most don’t have bank accounts is that there isn’t enough profit for the bankers at the moment. Bitcoin and Lightning fixes this with better technology.

I don’t see how giving the citizens of your country the option to save their wealth in a peer-to-peer alternative to traditional currency, powered by a hard inflation policy that cannot be manipulated by any politician or central banker impedes that solution. If anything giving the citizenry a Plan Bitcoin option would seem like a honking good idea to fight inflation. Just look at Venezuela, Libya, Syria et al for recent examples of how Bitcoin helped citizens of those countries.

Is the argument that Bitcoin won’t help them at all or that Bitcoin alone is not the whole solution. (I agree with the latter)
