"...if I pay a plumber to fix my tap, I don’t ask him to leave his toolbox so I can fix it myself next time; ..." Well, but I do have the right to go to the next DYI market, buy these tools and use them myself. Of course, I can't claim a warranty from the plumber if anything goes wrong afterwards. It is just much more convienient for me to ask the plumber to do this job, because he sells me his knowledge and skill in doing things that I could only do much slower in a much poorer quality. That's how far the similarity goes here. Problem is that as a coder, there is no clear distinction between the tools you use and the result you produce with them. So in the end, I'd understand the author.
