I can see the reason for adding some kind of anchor to the figure being raised but the value I would extract from this resource is completely orthogonal to whether it was written whilst living in Monaco or Mumbai. Putting it another way, for almost any other product on HN we would point out that one should price based on perceived value, so I find it curious that we are so happy with some kind of "labour theory" here. (Of course, there are other side-benefits to simply being an author of a book, so it might be worth discounting)
