That is true. I was imagining the AWS egress costs at my own work where things are going to so many places with latency requirements that the idea of sending hard drives is simply not feasible, even with infinite money and pretending the hard drives had the messages prewritten on them from the factory. Delivery would never be fast enough. Infinite money is not feasible either, but it shows just how this is not feasible in general in more than just the cost dimension.
