This is something I've often thought about with regard to organic farming. A claim is often made that modern agriculture and growing methods can decouple food's nutrition from traditional signals of nutrition like size and colour and blemishes. I don't know how true that is, but it seems like there's a branding failure here - that we somehow need to be able to select fruit and vegetables based on which specific producers made them rather than vague and inherently porous regulations governing what can be called 'organic' or 'natural'. Supermarkets might not like that - they'd have to better manage sales space to accommodate multiple known 'brands' of apples or oranges, but consumers would have a lot more reason to 'trust' self-interested brands of farms than they would an 'organic' commodity label. Any kind of a label that doesn't involve individual self-interested reputation but instead involves regulatory compliance is going to be gamed and ultimately ignored.
