Bear my ignorance for just a little longer, sage.
I throw money to a busker in San Fransisco. I do not expect I will
ever hear his music again, as I'll return home soon. Why might I do this? If you say "the social contract" again, you undermine your entire argument by providing a counteracting force to this "disillusionment"; a sustenance that prevents neanderthals like me (and the airport waiter who rarely sees the same customer twice) from going extinct.
In a society of machines, your arguments might hold. But ours is a society of people, the vast majority of whom don't even know what a "bit" is. Even if that comes to change, our nature will not.
