"isn't really making any constructive or lasting contribution to society"
The common argument is that if you are increasing overall efficiency, that means that capital can be more readily available for real businesses which do make lasting contributions (often in the form of polluting the environment, but that's another question).
It seems your argument is a bit simplistic. Couldn't the same logic be applied to the distribution of goods, middlemen, marketplaces, banking, etc. Are you dismissing all those?
