Dave's whole line of argument, that his not buying the animal won't stop the animal from being killed, is just one step removed from hand-waiving "no ethical consumption" as some free pass.

Where that formulation was initially intended as a confrontation, to invite us to think about how to move more thoughtfully in a society that would have us move thoughtlessly, it has contrarily become a thought-terminating cliche, a mantra for opting out of culpability for our own participation.
That an entire system exists, that POSIWID, is presented as the harm being done by the system, with us outside that system, the system being an external locus of control: Ourselves powerless before it.
The system, however we may choose to name it, is reified as a demiurge, creating and destroying the world without our having any part in any of it. My not buying the animal won't stop God from killing the animal, so at the very least let me buy the animal God commands a greater sacrifice for.
