I agree with you on the juice, but I strongly disagree on your conclusion. Sure, eating raw fruits and vegetables is fine — but it’s not nearly as convenient as you make it out to be.
1) You have to buy them. And buy them often, because they don't store for long. Sometimes the supermarket will be out of specific fruits completely, sometimes they will still be green, sometimes they will be brownish.
2) You have to be careful of how to store them.
3) With a lot of produce, you only have a couple of days until it goes bad. Just this morning I had to throw away half a broccoli that looked and smelled funny to me, and the eggplant is starting to look like my grandma. I bought both of them on monday.
4) You have to process fruits and vegetables to eat them. Washing, peeling, slicing, some you have to heat or soak in water, and you get a lot of waste and stuff to clean.
Not acknowledging the hassle that is linked to eating fruits and vegetables is — in my opinion — just as ignorant as selling a useless $400 kitchen appliance. If you enjoy this process, then great! Good for you. But if someone doesn’t enjoy it, or if they got little time in the morning, then I don’t blame them for attempting to look at alternatives.
Personally, I think a better alternative to juice packs are prepackaged smoothies. But unfortunately they contain preservatives and are heat-processed for better shelf-life. They are great for when you’re on the go, but not ideal if you’ve got a little bit of time. So I’d propose that a better alternative to proprietary juice packs would be a sort of air-tight smoothie packs: chopped up fruits and vegetables that are kept fresh in a special container (like an aluminum capsule) and that you can open and add into any blender. That would make the process of making your own smoothies much simpler, particularly when you want to experiment with different ingredients.
For fruit, there’s already a good solution: quick-frozen fruit. Fruits like strawberries actually keep much more vitamins when quick-frozen compared to “fresh” berries that have traveled a day and sat in a shelf for hours. Vegetables on the other hand often have to be heat-treated before consumption.
