Bhagavad Gita, Chapter 3, Verse 16

He who does not follow this wheel thus set revolving, living in sin and satisfied only in the senses, O son of Prithâ, he lives in vain.

Opting out of that whole cycle of give and take, living only for personal pleasure, doesn't actually lead anywhere good.

Society and nature run on a kind of exchange, contributing something back, not just consuming. Someone who only takes and never participates in that cycle isn't living a neutral life, they're actively working against something that was meant to sustain everyone.
