Hyperinflation is just a symptom of other broken things in those places, and the real solution is to work on that brokeness.
You don't paper over lack of trust with a system that sort of works around lack of trust, you increase trust. Otherwise you'll be screwed in a million other ways that have nothing to do with money.
It's all well and good to talk about fixing brokenness, but it's not always politically viable. Furthermore, even when it is, people still have to go around living in the meantime. "It'll be solved eventually when everything is made perfect" is not a reasonable approach, and people are well aware of that. A very popular saying where I'm from goes, "the strictness of the law is mitigated by not having to follow it".
What you want is a monetary system that is inherently trustless.
Let the policy makers deal with policy and legislation. But let's not let them mess about with our money any more. Anywhere.
(Even more so in the third world, where quite a few people have personally lived through periods when government printed money like crazy, and saw first hand how it starts and how it ends.)
