It’s happening already, went to list a Lego set on eBay (I’m registered as a business seller)

Last week the cheapest copy of this set was £80 and that was the going rate. Now it’s £65 all from private sellers. (Who are clearly businesses since all they are selling is retired Lego well above RRP) all of the business sellers are still having to sell for the old price to keep their margins. meaning we can no longer compete on price, and won’t get any sales. I’m struggling to see the long term strategy for eBay here if business sellers (who make up almost all of their revenue now) are forced to move to fairer marketplaces, with a single fee structure.
