The biological part is seeking out a desirable mate (per my amateur understanding of biology - it could be completely wrong). Desirable for many animals includes ability to procure resources (and defend them). Being able to consume displays this (and not necessarily plastic things). Consuming leisure time and activities are a signal that you have the power to do more of what you want to do or obtain it.

But I do not claim this is a scientific conclusion, I simply landed on this model as it seemed to match up with my reality.
