I'm saying whats important is the quality of the resulting house (we maybe extending the metaphor too far here). If you can make a better/higher value/more usable house with an inflatable mallet then with a nail gun then yes that may be the right choice.

Absolutely, and note I'm not taking shot at Lisp as a language. My argument is with the article, there is nothing here that supports his premise that Lisp is for entrepreneurs. That it was the right choice for a couple of cases? Sure! but for anyone starting a software business? nonsense.
