You are missing the whole idea of minimal pricing. If you sell your apples, and I sell my apples, I have no right to tell you what minimum price to sell your apples at.
However, the minimal pricing that is discussed here is wether or not a manufacturer has the right to say "Don't sell my product below a minimum price". Essentially, it is used by manufacturers to artificially keep the value of the products up.
A lot of automotive parts manufacturers have this. Also, some manufacturers (Royal Purple Synthetic Oils) refuse to sell to Walmart, because they fear by doing so, would lower the selling price and perceived quality of the product.
I feel that if the courts do not allow manufacturers to set the minimimum selling price, then in a certain way their rights are violated. If I produce high quality apples that you want to resell, why shouldn't I be allowed to limit the minimum price you can sell them at?
An optimist believes we live in the best world possible; a pessimist fears this is true.
