a) there's no way I can prove that my pleasure in eating the cheese is genuine and authentic and instinctive and isn't a response I've conditioned into myself because I've come to believe that liking expensive cheese is something I ought to do...
I see where you're coming from but I think going down this route can only lead to crippling self-doubt and quite possibly madness. If you like Product A better than Product B, and can afford the difference in cases where A is more expensive than B, then buy Product A. I don't see any benefit in having some great analysis over whether the pleasure derived thereby is 'authentic' or not.
