Yes agreed. Assuming software engineering context here, not civil or mechanical or other mature industries which usually require millions to create, validate, test and release a new product.

Negotiation of requirements is a problem based on limitations like recources (money, people), known knows and known unknowns.

Ah yeah, I tend to not think of what we do (or at least, what I do professionally) in the software field as engineering for that reason. What we do seems closer conceptually to carpentry rather than engineering. Not that changing things to be more engineering is necessarily better, of course; much of the benefits of software _is_ the flexibility.
