Can't blame them. Lives are based around fiat. We pay for food in fiat and it's the unit of measurement for "value". Although Bitcoin is a currency, we can't actually directly live on Bitcoin just like we can't live on a foreign currency away from it's country of issue.

There are still a lot of users who are interested in Bitcoin for its core values. The biggest irony I think, is Bitcoin being most useful to those in economically and politically unstable countries, and not enough people there have caught on to Bitcoin yet.
