Like a sibling poster, I hear this a lot too, but I don't see it as all that significant. Or, rather, these are excellent uses, but Bitcoin is a terrible way to accomplish this -- it's just a huge shame that there may not be better options.

An actual currency should have a stable value. Bitcoin will never have a stable value (at least not while it is popular) due to speculation. People who believe Bitcoin is a safer store of value than their country's fiat currency are in dire, dire straits indeed.

I do absolutely agree that people should be free from fear that their currency of choice/necessity should be safe from the possibility of 100-1000% inflation per year, but I wish we could do better than Bitcoin, of all things, as a "solution".
