" I was actually asking to see if people agreed with me that different economic systems could co exist in the same area"
"in the same area" is not the same as "in an anarchist society". but for now i will assume you mean both. because we are talking about an anarchist "society", the first question raised for me is: why would there be an economic system (let alone many) in an anarchist society? but then i have a rather anti-mass perspective, and economic systems kind of require a mass mentality. as does production/consumption that extends beyond the immediate needs (and desires, for whatever that distinction is worth) of the individuals involved. if i grow more tomatoes than i (and my clan) can use, what do i do with them? of course, whatever the fuck i want, including composting them for my next garden or throwing them at passers by. but if my neighbor wants/needs them, and i choose to interact with them at that level, i am totally open to either gifting or bartering those tomatoes (depending on the nature of my relationship with said neighbor at the time). if i sometimes gift, and sometimes barter, with other individuals in my bioregion, what kind of economic system would that be? you might say it is 2 different systems. i would say it is no "system" at all, it is individuals choosing how to relate with each other and how to utilize what they want/need/have/create based solely on the context of that situation. an economic "system" does not (to my understanding) allow for that kind of fluidity and flexibility, let alone autonomy. i could be wrong, as i have no formal background in economics.
so perhaps my issue is with the assumed need for economic system(s) in an anarchist world.
then again, it could just be my crack pipe again.
