Having children and dogs is already expensive, and has other "opportunity costs" which somehow balance the positive sides, so that I do not end up with 3 thousand dogs and children fooling around my house.

All-included Prime Delivery with zero delivery costs (because drone costs will tend to zero, and anyway Amazon is happy to cover the costs because they save on other delivery methods), will have as a consequence an unbound amount of underpants flying over my head. So I need some externalities added by the government to balance the situation.
