That's good. You're sensing that something is wrong.
>> If you insist everyone make every moral choice for themselves, then we will be unable to maximize the "right" choices
Why would "we" need to "maximize" the right choices? Who's we anyway? Aren't we all just individuals, with our own goals and desires that are constantly changing anyway? Who's anyone to "maximize" the "rightness" of your choices, as long as you don't harm others? How bad should you want that bar of chocolate tomorrow at noon? What about in the evening?
See, economies consist of exchanges between people, and whenever an exchange is voluntary, it leaves both parties better off.
There's no "optimization" necessary there. It's all based on each individual's subjective preferences. If you want an apple, and have a dollar, you can give that dollar to someone in exchange for an apple. If you do this, it means you valued the apple higher than your dollar, and the other guy valued your dollar higher than his apple! -Bam. Both are better off. No "maximizing" necessary.
>> In a libertarian society, every person would need to be educated on food systems, why some are ethical and why some aren't, etc
Really? Is it really unclear to anyone that treating animals well is better than treating them horribly? Why would anyone prefer the meat that's produced through treating animals horribly, or even badly, compared to a more "organic" alternative?
Sure, prices are a factor, but just about everyone would like to support treating animals well, right? So if organic production is increased, those prices will fall. It may still be a bit more expensive, but organic, non-GMO food comes with the additional benefit of not being harmful to your health, and that's quite valuable too.
>> nevermind the 3 year study and expert panel that analyzed the issue and recommended process/measure/regulation X.
Who are the "experts"? -Where do they come from? What are they affiliated with? Who paid for the study? What kind of regulation are we talking about? Why would it be good? What's the alternative? How often is coercion better than no coercion? (Pro-tip: never)
.. And so on.
