This is simply not true for most software. Software has a product life cycle like everything else and major refactors/rewrites should be weighed carefully against cost/risk of the refactor. Many traditional engineering fields do much better at this analysis.

Although, because I run a contracting shop, I have personally profited greatly by clients thinking this is true and being unable to convince them otherwise.
