We may not like it, but your last point is almost the exact definition of what a "price" is. Things don't have objective "prices" as an intrinsic quality. They don't even have "reasonable" prices intrinsically. A price is no more, and no less than an agreement between buyer and seller to make a transaction happen.
"how much you can be fleeced into paying" while a proactive way to phrase it, is also "What you are willing to pay." Key words - "you are willing". If it's too high, then it isn't a price, as there is no agreement.
Seller wants highest price, and buyer wants lowest.
When it's a commodity, like apples at the store, with many sellers of a basically undifferentiated product, prices average out to something we think of as "fair." But when a product is unique, or there is a monopoly on it, seller has a huge advantage in pricing.
