I *may* go so far as to say autarkeia has, in part, the connotation of being content with one's economic situation if at least all your basic needs are met. Which is not to say one has to be satisfied with a mere subsistence existence!! There's nothing a priori "bad" about accumulating wealth (like the property manager talked about by Philodemus) but don't get caught up in making money for money's sake. The goal of wealth is still the living of a pleasurable life and being able to give to your friends if needed.
I *don't* think Epicurus advocated the complete removal from society and the establishment of autonomous communes away from the polis. The Garden was a community but not a commune. I don't endorse that connotation of autarkeia. Even "live unknown" had connections to society. How else would the wise establish a school but not draw a mob. How else would they give speeches if asked if they were off in the woods or cut off from society?
I'm also not convinced that the Garden was residential. I think some close affiliates like the "guides/teachers" lived with Epicurus or near the Garden, but I get the impression it was more a "commuter school" for the most part. But I'm still doing research on that.
NOTE: I'm not saying you're necessarily advocating the viewpoint I'm talking about in the last 2 paragraphs, Macario , but I think there's a strong strain of this out there. So, I figured I'd get my position on the record... or at least my position as of the writing of this post. As Cassius says, I reserve the right to revise and extend my remarks ![]()
