We don't need to transform the universe into something we feel dutifully obligated to create, but isn't really much fun - in the same way that a Christian would feel dutifully obliged to enjoy heaven - or that some strange folk think that creating orgasmium is, logically, the rightest thing to do.

It doesn't seem impossible to me (only unlikely) that orgasmium is really the best thing there could be according to our idealized preferences, and far better than anything we could be transformed into while preserving personal identity, such that we would be dutifully obligated to create it, even though it's no fun for us or anything we identify with. I think this would stretch the point somewhat.
