In my limited experience of seeing Dutch auctions in practice it actually has the opposite of the intended effect, as the people that are willing to pay the highest are also the people that will have a way to profit, just on a lesser scale.

For example, Panini (sports card manufacturer) did Dutch auctions on boxes of new card sets during the peak of pandemic collectible mania. The majority of customers that were willing to pay the highest prices on Panini's website were card breakers, which are people/companies that sell "spots" in livestream box openings (i.e. customers buy the right to all cards containing players from a certain sports team before the box is opened).
