Push a comment to the extreme and of course it fails. The point that takeout makes more waste than cooking at home is very real. I don't do anything crazy, have a landfill I'm my yard, etc. My neighbors had a family the same size as mine. Each week their trash cans (2 of them) would be overflowing and my single can was 3/4 full, sometimes​only 1/2. The only real difference - they ate tons of takeout, ready made it frozen and we eat out once a month and cook our own meals.

Yes my pasta comes wrapped in plastic and my vinegar in a plastic bottle like everyone else - but it doesn't compare to the waste of takeout and frozen dinners.

Can you buy a pocket full of rice? No, but why would you? Buy a huge bag at Costco and see how long that lasts. That is how you reduce waste per meal.

The comment above you had a ton of examples of where you couldn't get something in a re-usable package, and you responded by shifting the goalposts to just using less plastic.

One person above suggesting produce, then someone responded about pasta, hot sauce, and other things that aren't produce.

Even letting slide that moved goalpost, some things requiring packaging doesn't merit disparaging the idea of reducing packaging.

In my case, I stopped buying pasta and mostly replaced it with legumes, which I buy from the bulk food store with bags I bring with me, so I've achieved the same effect. As best I can tell, the legumes are healthier and taste delicious in my stews. Plus I've learned to make more foods in the process.

The point is, even if you can buy produce without waste (which you totally can at a grocery store too, my bell peppers don't come covered in plastic), there's more that goes into grocery shopping than just raw produce. The goalposts were "making entire meals", munin was the one who moved them up to say "look how easy it is, all my produce is waste-free". It doesn't matter when everything else you need to make your meals comes in non-reusable packaging.
