Whether that compensation comes in the form of a discount to the price, compensatory miles, or a voucher isn't important, but the acknowledgement that they are providing diminished service is. We shouldn't accept "Sorry, those are the rules" as an excuse.
Many people pay premium fares and/or are otherwise entitled to various perks but do not take advantage of them: 1) club(s), 2) alcohol, 3) food, 4) checked luggage, and so on. There are flights where alcohol cannot be served or cannot be served on the ground and so on. Nobody gets discounts, vouchers or anything else.
This is about obeying the law and it's the carriers' and the pax obligation to do so.
