Of course, the analogy falls down–like all analogies–at some point. However, there is a whole realm of industrial fabrication beyond what is available at a simple/hobby shop. To put it a different way: there are tools that I want to use when I am making one of something. Then there are different tools when I am making 10 of something. Again at 100, 1,000, and 1,000,000. I've been a teacher, and I think there is a inherent conflict: As a teacher, I want my students to learn _how_ to do something, but I also want them to do things "right". Those two goals are often at odds. Sometimes the best way to learn is to do it "wrong"; preferably in a safe environment where doing it wrong won't kill/maim you. I think the injustice is trying to teach students how to use the "for a million" tools (which they will _need_ later), when they really struggling with the idea of making one.
