Why should it be demotivating trying do something perfectly as requested?

Many of us, including me, come from freelancing, and perhaps that trained many to answer most customer requests with "ok but what you really want is...", but in a company where there are people doing that as their job... Why bother?

Actually I would even go further and argue that too many passionate developers talking product management in every refinement meeting is a big inefficiency, and depending on the company size, sometimes even one is one too many.
