You are usually very healthily critical of things that are said by people. However, when it comes to Elon Musk, you seem to assume that whatever he says will be true. In this article you use one of his statements as proof that the price of the payload will drop to the level that Elon Musk says. I find this different treatment of sources quite dissonant.

Two things this article brings to mind. 1) Early U.S. we settled around the waterways for precisely the reasons you mention. In KY, for example, corn was converted to bourbon and ham so it would not spoil. Waterways were used to take them to market. Eventually railroads became transportation hubs and then population really began to disperse when the roads/automobiles came. 2) The discussion of weight and how engineers worked to make every ounce count reminds me of the early years of the microcomputer industry when programmers worked to make every bit of memory count. It was in short supply and thus you had to make efficient/effective use of every bit of memory available to you. Today that is not a problem and if you look at the code of many programs they are not efficiently written.
