You do realize you contradict yourself here, right?

You’ve essentially said “This activity that amasses stays and resources has negligible fitness value.”

That only makes sense if you think status and resources don’t impact fitness/survivability. You might be confusing inherent value with signaling value. Driving a Ferrari doesn’t give me any additional inherent fitness. But it does serve as a potential signal for status, which can confer added fitness in practice. Signals can be wrong, of course, while still giving an advantage.
