The Venezuelan Bolivar is even worse.

If you saw this happening to a close neighbour then you would also be worried about your own currency.
Not saying that bitcoin is the salve they need, just that perhaps given that context you can understand why it appears like an attractive alternative to the local currency. Also USD and EUR may be better options but I dont think having accounts denominated in these currencies is easily available to many people in Venezuela or Mexico. I have only (last 3 years or so) been able to hold EUR or USD denominated accounts (relatively easily) and I am in the UK. I'm sure it was possible to do for longer than that but it required hoops to be jumped through that are not always the easiest.
