There is a large movement of farmers in the US intent on growing the best tasting fruits/veggies without the aid of artificial means/processes.

Yes, this is still on my point. Technically Monsanto isn't aiming to decrease the quality of taste in food, they're sacrificing it for marketability. A farmer trying to increase profit but not yield GMOs will naturally select the exact same traits for their crops, that Monsanto will genetically modify for its clients. In this I believe they have the same definition of best.

Now, a farmer who disregards increasing profit potential will take a slower "noble" route of naturally selecting the best tasting crops, as you said. It is the product of counter-culture which exploded ironically (again, counter-culture) into what is now indistinguishable from the mass market-- see Whole Foods-- that allows those farmers to still make enough money to stay competitive in the market, because Whole Foods may explicitly ask for those delicious ol' heirlooms. Without places like Whole Foods, a farmer would have to potentially decrease taste in the process of increasing marketable eye-appeal just like Monsanto would, even if the local farmer's means were not genetic modification. I don't think we're on opposite ends of the table, I'm just shit at explaining things.
