I am not sure agree with this concept of friction, though I agree with the intention. Deliberately introducing friction could be viable temporary means of managing a system which is broken, but it won’t successfully manage it forever. A better solution is to fix the system. In the case of our society, as everyone is continually competing with one another, deliberate friction mechanisms are needed to prevent the more powerful destroying the weaker. Hence the reason we need politics, law and order, and government (Though arguably they themselves are becoming part of the problem). What if all of our interests were aligned? If we were all working to the same end, to add value to our society, our world, and thus us ourselves, being infinitely rewarded for that, we would not need or want friction in the system, we would want to maximise the frictionless input of every individual, to get maximum value adding effect.
