i feel like every activist should read about fruitlands.
fruitlands was a transcendentalist utopian commune founded in the 1840s. the founders (including louisa may alcott's dad) thought that the existing capitalist economy was evil: alcott described it as a tree “whose root is selfishness, whose trunk is property, whose fruit is gold." so they decided to create a commune that was completely divorced from the economy. like, their response to the "you say you're against capitalism but still participate in it! checkmate socialists!" people was literally "you're right, let's not!"
they refused to consume any materials or foods that couldn't be locally grown, like tea or sugar. they were also highkey vegan: not only was it immoral to eat animal products and use animals for leather and wool, but using animal labor or even using manure as fertilizer was forbidden. and they refused to trade for anything they didn't have within the commune because participation in an oppressive economy was bad, especially if it supported slave labor (ex: wearing cotton fabric).
it fell apart in less than a year because they didn't have enough food to survive the winter.
well, part of it was circumstantial: the site they picked had little arable land and they arrived a month behind in the planting schedule. part of it was the impracticality of living in the 1840s and being so vegan that they couldn't even use oxen to plough their fields or wear clothes that were warm in cold weather.
but the main reason was that the men of the commune (and they were almost all men, except for alcott's wife and another woman, ann page) didn't actually, like, do anything. they left all the household chores and childcare to the women, plus most of the farm work, while they sat around and philosophized about how cool their utopia was. even before it fell apart, most people there had began taking "vacations" away from fruitlands so that they could take hot baths and avoid trying to till the soil with their bare hands.
there are a lot of good lessons here.
1. it's very easy to talk about your great ideas for society but putting them into practice is much harder. you have to actually do the work to achieve the goal: you can't shunt it off onto other people based on the same oppressive systems you're trying to subvert.
2. you need to consider the practical implications of what you're arguing for, including potential downsides. banning wool for ethical reasons is all well and good until you're stuck wearing linen clothes and canvas shoes in the middle of a massachusetts winter.
3. you can't expect that a utopia is going to be all the things you like about society staying the same and everything you dislike being changed. that is at best naïve and at worst intensely selfish.
tl;dr: talk is cheap, praxis is hard.
