What is the point of the "Buyer's Premium"?

Does it seem likely to you that nobody ever forgets about it? Does it seem rational to you that this complication would be added (a system is easier when there are fewer variables) if it did not produce a better result for the house?

Would you be happier if I posited instead that auctioneers are too stupid to figure out why their business model is what it is?

This isn't much to get offended over in the idea that people running businesses tend to structure them to their benefit when possible. A Buyers Premium structure, with a separate fee to tack onto the bid, is not designed to the benefit of the buyer. This seems like common sense. If you would like to take this as a personal slight on your aforementioned list for some reason, go ahead.
