This is true for any case in isolation, but for all consumers in aggregate there is no other way to do things that ensures an increase in everyone's wealth.
Any kind of flattened pricing structure will always harm some consumers for the benefit of others in a sufficiently large market. If I'm willing to pay £12 for X, you're willing to pay £8, and the producer is asking for a flat £10 because people like me find price discrimination morally abhorrent, then: I get the utility from having X plus a bit more from the £2 kickback; the producer isn't fulfilling his goal of profit maximisation and has incurred an opportunity cost of my £2 + your £8 = £10; and you get nothing. I'm the only winner, and the £2's worth of economic value I've gained by enforcing an unfair pricing structure is less than the sum of the value I've deprived you and the producer of - my behaviour is tantamount to stealing a small slice of yours and the producers combined utility and burning the rest.
The only way around this is to find a way to set price equal to true valuation on an individual basis. Of course, if you allow your model to not be Pareto efficient ("there is no change that could be made to benefit someone without harming someone else") then there are much more efficient ways to steal wealth than flat pricing.
