You are forgetting opportunity costs in besmirching "build fast" over optimising for TCO. If I can use the code to gain an immediate business advantage it is entirely possible that I'll take something in 3 months than 6, even if it costs more in the long term. The language, and negotiation, required is of the Engineer, not the Scientist - there is still optimisation going on.
