I think it depends what aspects of "cooking" you value.

Some people really enjoy the meal planning part. Some people really enjoy picking out fruits and vegetables at the store. But others don't like planning out meals for the whole week and find grocery store trips stressful and frustrating (maybe their local store is incredibly busy). Blue Apron has a value proposition for those in the latter category who also enjoy the part of cooking that starts once you've got the grocery bags in your kitchen.

I assume you don't grow all your own produce, or slaughter your own meat. My extended family does (at least mostly) and they would claim that I would have a more satisfying life if I did as well.

Where one draws the line at doing it all on your own depends on time available, motivation, and opportunity cost. I'm not going to judge people whose utility function is different than mine.

> You put effort into something, your satisfaction goes up.

I enjoy menu planning, shopping, and cooking more than most people.

OTOH, I also enjoy ballroom dancing, and a variety of other non-cooking hobbies. Sometimes, I want to devote lots of time to cooking. Sometime, I want good food at home with the care I (or my wife) puts into cooking without the rest of the organizational and planning overhead. Blue Apron excels at the latter case. It's more packaging than I'd prefer, and than I need for the use case because I have a pantry well stocked with basic essentials (which is where the worst of Blue Apron's packaging excess tends to be), but for something that works in a diverse market and without gotchas, I see why they do it.

Everyone's different. You can't expect that everyone will derive the same satisfaction from the exact same activities as you.
