As a business seller i'm paying upto 30-40% costs & fees, seems crazy. & no I don't want less formal sellers to go. 

Money - starts out as dept iou's (see David Graeber) then to coinage (basically for war/plunder because it's not linked to anything, mobile) ...& then people start collecting it like that's the valuable thing & use it to extract value from others subjugation via their monopoly, ..Ebay has us just where they want us, a cow to milk. & their class set state policy to keep us all with less so we need them more. Just an extension of UK enclosures  act really.
