When I talk about economic problems I'm talking about how Bitcoin can solve today's problems by replacing our inflated currencies with one that cannot be printed with a click. Taking a look at countries in very harsh situations such as Venezuela, this inflation could easily turn a whole nation's net worth from 100 to 0 in the snap of a finger.
Right, however, for macroeconomics problems, the essence is still the same, i.e., scarcity and distribution of resources. Even with Bitcoin, Venezuela wouldn't suddenly become more productive so that more goods and services produced.
The job of a government is to distribute the resources efficiently, and inflation (price increase) is a symptom that there are too many demands for goods and services compared to its supplies, not only related to the amount of circulated money.
Bitcoin might, however, prevent corrupt governments from playing around with its currency supply. With Bitcoin, governments wouldn't be able to mask its unproductivity by artificially print more money. Hence, I agree if Bitcoin could be useful in countries like Venezuela, etc. However, it wouldn't magically solve the fundamental economics problem overnight.
