It's the single one and only thing you said you value. And you didn't say it's what you value, you said it's what "we" value.
All I'm asking is, what besides effort do you value in art?
It's the only thing you said "we" value. I argued against that claim, and you pushed back. I asked you what else you value, and you pushed back. So don't come crying now, about how effort isn't the only thing you had in mind.
In fact, we've reached the QED stage. You said you valued art because of the effort. I said, no, you value it for other reasons. Now you're saying yes, there are other reasons, distinct from other things that require effort, that cause you to value art.
So yeah, I was right.
