A lot of that buyer protection is only needed because of a system that is prone to fraud because of bad design. ie: your employee can steal your customers credit card information and sell it. That kind of fraud is _not_ possible with Bitcoin. So the one thing that is left is the case where a company is dishonest and doesn't provide the product or refund. There is no reason that the dispute mechanism has to be linked to the payment that problem can be solved over time for those who want it.
