I chose food processor for a few reasons, btw, just in case this helps inform the discussion.
From a personal level, I genuinely would be far less capable of looking after myself, without mine (I have an amount of loss of function in my fingers, making chopping very difficult, but not impossible)
SO: it wouldn't be impossible. So, it tips into the "nice to have, but not 100% necessary" - it's not *quite* on the same level as my eye-glasses, or a wheelchair, but it's *important to me*.
Also - trivially obviously - they require manufacture. It's not like my apple tree where I have more apples than I can use, and therefore don't care if you want some. Someone, somewhere (someones plural, in fact) needs to make decisions to manufacture them, with all of the downstream supply chain issues that implies.
And that choice to manufacture the food processor that I've fixated on might involve *not* making something else.
(I'm okay with the assumption that it's not made from plastics that cannot be recycled, and so on, in a non-capitalist world, and would be more modular and robust, and more fixable and so on - I would make those assumptions myself)
