I like your explanation. Everyone has different views and needs, it influences his decision in determining whether bitcoin is really needed in his life or not. I as a freelancer, place bitcoin as an alternative in getting additional income through trading. For money transfer activities, I still use bank transfer in full, because the circle of ecosystems in my environment is still not familiar with bitcoin.
On the other hand, there must be someone who really needs bitcoin to make large money transfer transactions, saving time and effort because he can do it without a third-party intermediary. In general, I would say yes, we need bitcoin, either as an alternative or as a top choice, there are many advantages that we can use.
