Fiat money system is really hassle free and very flexible in payments and transactions unlike bitcoin. Yes, bitcoin have some its good traits like being untracable but it's fees are too high
Every currency system has some advantages for the people and at the same time they have certain limitations as well. The major disadvantage of fiat currency system according to my opinion is that it has more time wastages in processes globally as well as locally.
World is getting competitive day by day, so it is better not to waste time while standing in the queue and do something productive in that time and thats what bitcoin is offering.
