I have copious evidence that what I consider "beautiful" is different from what some other people consider "beautiful;" I have copious evidence that what I consider "fair" is different from what some other people consider "fair."

But there is little upshot to people having differnt notions of beauty, since people can arrange their own environents to suit their own aesthetics. However, resources have to be apportioned one way or another. So we need, and have discussion about how to do things fairly. (Public architecture is a bit of an exception to what I said about beauty, but lo and behold, we have debates at that too).
