@cliff_spab People ask me what happens in Anarchism, how do you get medicine, food, clothing, etc. As if there are not people deeply passionate and knowledgeable about these things.
It's not some magic 'hope it all works out for the best', it would require active work and figuring shit out. But ultimately, people want to help people, and even if you want to argue the self-interest shit, it's in your self interest to join in the community around you.
It's all inertia.
