I feel the argument but I think I would need different examples to better understand.

There are reasons for owning a watch other than "tell the time," which could include "tell the time accurately without ever needing to change batteries," or "tell the time and date," or "tell the time while scuba diving."

Rolex may be overkill but different watches serve different roles, and it's not just brand name alone that makes Rolex cost orders of magnitude more - in many ways, it really is just that much better of a product. Same for Camry vs Porsche.

An Apple product, particularly a Macbook, on the other hand, not so much. It's a nice aluminum chassis over crappy, cheap internals that break so often people throw around words like "class action" to describe the keyboards. It's like cramming a knock-off Timex movement into a Rolex case.
