Is that an actual EA argument?
The value is all at the margins. Like Carnegie had legitimate functional businesses that would be profitable without Pinkerton's. So without Pinkerton's he'd still be able to afford probably every philanthropic thing he did so it doesn't justify it.
I don't really follow the EA space but the actual arguments I've heard are largely about working in FANG to make 3x the money outside of fang to allow them to donate 1x ~1.5x the money. Which to me is very justifiable.
But to stick with the article. I don't think taking in billions via fraud to donate some of it to charity is a net positive on society.
