5 seems to suffer from the appearance of creative tunnelvision. You can absolutely find your way through a tool, and should be encouraged to try as many as you can. The more useful lesson is to learn not to rely on it. You don't have to learn that lesson by pretending your relationship with your equipment isn't as big a factor as it is.
To note -- I really enjoyed the essay, and don't think the intention was to stifle anything, but instead to tell people exactly what I just wrote.. That's just the way I think it is being read into.
