I think bitcoin's main benefit is it avoids censorship. If Visa and Paypal refuse to work with you like they did with wikileaks/mega or any other sites they don't like the look of then bitcoin liberates you from that tyranny.
This is good but I usually see skeptics asking this and they don't get convinced no matter what argument you make.
More fool them if they miss out on the revolution. Maybe one day they will regret their decision.
Of-course they will, like I am for not getting into Bitcoin really early like some of the early adopters did or my life today would be so different.
