perhaps it is, but I'm not convinced. if food, eating, whatever were an unnecessary and wasteful system then the growing of food and processing, production, etc would likewise be a waste of resources, human labour included. a lot of our work does go towards food production, supply, processing, etc - if you could switch to an alternate system that dispensed with food but didn't otherwise alter our lives, that would surely be massively preferable. it's hard to imagine because eating is such a fundamental need, but that's just a limitation of this comparison.

if we could dispense with money but otherwise have society look much the same (or better, which I think it undoubtedly would be), that would be an improvement, to me, just by virtue of freeing up the labour of all the people who work solely in the overhead of the system. to imagine how else we might function as a society, I think it's useful to identify ways in which the present system is inefficient.
