I agree and also their is not buyers protection if you purchase intangible items.
Paypal may as well have a banner on their site saying 'Fraudsters please use us as we will 100% support you'
i.e. you set up a flashy website that list downloadable software (which you dont have) and use paypal as the payment method. You get people order this non existing software, so this does not arrive, so you set up a PP claim, well this claim wil be closed as its intangible, so in a way PP has supported the fraudster as they have your money and you have no goods and PP will do nothing to help.
