[el-salvador]

Based from what I've seen form the rule of law system in El Salvador for the past months...

That the most possible answer is that...

Someone from the government tweeted or said that they had to do it on a tv interview, otherwise they would officially face fines or perhaps closures.

Yeah, isn't it a legal requirement subject to penalties, as you say? Then surely it's fair to measure success of the program on those terms as well -- i.e., is it being used as a currency for daily life? The answer is seemingly not (for technical, social, and speculation reasons), meaning it's fair to comment that this part of the project seems to be a failure. OP can't carve off criticisms they don't like or _personally_ care about.
