Developers tend to "over-decouple" when attempting to accomodate for "possible change". (And how often do such changes really wind up hiding behind a pre-exiting facade rather than requiring some larger code refactoring anyway?). I agree with you that an even bigger driver of decoupling than such evolutionary considerations is the need to break up a system so that it can be built by multiple people or teams working in tandem. Too many architects overlook such "buildability" considerations when devising an architecture, but they're cross-cutting concerns that need to be considered along with all the more commonly discussed concerns (scalability, availability, etc) that drive the definition of a system architecture.
