Not only is this not some kind of "genius" evil scheme, this is in fact the only way that makes sense at all. If you could buy a Tesla with Bitcoin with a guaranteed refund of the same amount of Bitcoin, you could use it as a financial instrument. Buy a bunch of Teslas for Bitcoin, then if Bitcoin goes up you send them back for Bitcoin refunds, and if Bitcoin goes down you sell the Teslas for dollars instead. Now you can speculate in Bitcoin risk free! Obviously it can't work this way.

Actually the only fair scheme would be to always price purchases and refunds in the same currency. Of course that can't be bitcoin.
