Your fears are unfounded because it wouldn't matter to them. Most of the people you described are happy just to see food on the table. They're not going to care if they bought it with fiat or Bitcoin. Bitcoin does provide financial inclusion, but the sad reality is that you need to be doing adequately financially to take advantage of it.

At our level, nothing can be done to create lasting impact. Donations can help them not go hungry for a few days, and that's about it. Poverty is not the cause of the problem, it's a symptom. You have to go for the root, whether that's systemic corruption, or ineffective governance, etc.
