If you had to build a windows GUI from assembly code, almost all software projects would be too expensive. Instead we reuse high level languages and frameworks to start with the basics a program needs. To extend the metaphor to milk, what if the milk industry had to invent the glass industry in order to make the bottles which it comes delivered in? Consumers would have cows not refrigerators. The dis-economies-of-scale-software are programs where normal glass simply can't be used to hold the milk. A whole new custom type of glass has to be developed. And this usually for a type of milk only like 1,000 people even drink it.
