You missed to clarify that tourists use pesos convertibles which are artificially tied 1:1 to USD (1USD, 1 convertible) and that are basically what casas and taxi drivers accept. But you can totally go to local restaurants as a tourist (we did it a few times during our 3 weeks stay). And yeah, it can be sad to see how people lives there, and many try to flee but as you said makes you think about the real, deep impact of consumerism.
