All of these seem like solvable problems. E.g. in Manhattan Prime Now can already deliver within 1-2 hours. Stolen packages can be catered by drop-off safeboxes in houses/buildings. Job specialization should win in the end - a delivery person with an efficient route is going to be cheaper than the sum of everyone picking their stuff up.
