There are more advantages when you look outside the narrow view of utility in modern western society. Now anyone in the world can explore entrepreneurship and all they need is a computer. Computers are becoming more and more accessible (Raspery Pi's, $100 laptops etc).
Now people in poverty stricken countries can establish their own businesses and trade on a world wide scale. No bank accounts needed. Ability to accept micro payments without abhorent fees.
