Money is not a direct factor of who is interested the most so it is not necessary fair.

An example: my partner is working in a relatively expensive "wellness" service. Some people reserve and never show up even though they have reserved for a whole family and lose more than a thousand euros. I am pretty sure a lot of people that cannot afford this service at this price on a regular basis would if it was less expensive for them. I know I do as I only profit from it because I have a 50% discount and my partner doesn't have to pay so we pay a quarter of the price everytime we go together.

So making it an auction and you would still see a mix of interested people and vain but wealthy people for which paying for this would still be pocket change and would just take an "I've been there" selfie and move on without really being interested in the artwork itself. So more money for the museum but not necessarily representative of the interest of the visitors.
