Because I've read other, less entertaining writing on the history of money which concurs with Graeber's central argument that money is much best understood as debt accounting (and some pretty terrible writing about the magical powers of certain metals) and the sloppiness in illustrative anecdotes (or impractical utopian proposals of regular debt jubilees) doesn't really affect that central thesis. I wouldn't necessarily rely on Graeber's colourful anecdotes about historical civilisations or obscure tribes being accurate and uncontroversial without checking what other anthropologists think, but those are 'small picture' things.
