Isn't division of labour a capitalistic thing? That ultimately leads to alienation?

What is the limit of a "community"? I live in a city where it is certainly not practical to grow the food needed to feed the city inside thr city limits. On thr other hand, in my province there is tons of high quality land that would be more than sufficient to grow enough food for the whole province, especially if the food system shifted to a vegetarian-focused one. Thats a lot bigger than my "community" but it is a lot more practical and arguably more sustainable.

There's a level of food sufficiency one can achieve on their own, even without land. e.g. I'm putting together a medium scale hydroponics system right now for home - it needs 100-120cm of wall, 30cm deep at its thickest point, and can grow about 120 separate spots.

Now obviously hydroponics is not an easy answer for all food needs. You can't easily grow wheat and other grains/cereals in the volume you'd need. You can't grow larger fruits that require trees. Smaller fruits - tomatoes, cucumbers, berries are usually pretty doable. And of course tons of herbs and spices - rocket/arugula, basil, mint, you name it.

If anything, the herbs alone are worth setting up a small home unit, especially since it's so effort-free - add water, measure nutrients, repeat once a week, harvest in 3-4 weeks earliest, trim it proper and freeze for long term storage, and you don't even need to re-plant things because most of what you'd grow in hydroponics, when trimmed right, just grows again.

Again, this doesn't solve all the issues, but having some freshly grown herbs at least is a good way to get started with "grow your own", even if on full scale it's impossible.

Zucchini is easy to grow and yields a lot, so it's very popular for people who have vegetable gardens. Probably 90 percent of people growing food in North America are growing tomatoes, zucchini, and/or herbs.

Less parking more literally anything else

I'd imagine "without land" was aimed more towards "can't grow enough to be self-sufficient". You can totally utilize even small places very well, but if you're poor living in a tiny flat without much natural light it's a pretty daunting task to grow enough anything to live off that. Just the electricity cost for the lamps might make it pretty hard depending where you live. I guess mushrooms instead of vegetables might work a bit better though

It's making fun of unrealistic suggestions people make regarding potential solutions to divesting from industrial agriculture.

I am the purple one, as the land I have access too is whatever pots I can fit by my window which also doesn't have direct light.

People with health issues *that make them incapable of gardening in some way so must rely on the industry.

One would need to grow and preserve a lot of food to store away for winter and if a crop fails or the preserving technique didn't work they're fucked; thankfully one can just go down to the store... which is the main point of this meme.

I think zucchinis are the most efficient vegetable one can grow in their backyard or whatever, so one would be eating a lot of it.
