What's the added value of a human giving you toilet paper? Now both you and the hypothetical toilet paper merchant can go and do more interesting things, maybe you'll meet at a gym, bar or social event instead of the random and sometimes awkward social experience of a commercial transaction. The human gets replaced by a robot doing the menial task, win for everyone (as long as the pie expands and he gets another more meaningful job). Most new jobs are basically service jobs, so maybe now instead of handling toilet paper he'll give you a Starbucks coffee..
