I'm enjoying this, and I feel like it has been a meaningful exchange. I'm still not convinced, but I'm less unconvinced. :) Thanks for taking the time to walk me through the mechanics of it. That's the biggest piece that is missing when people talk in philosophical or general terms.
What I'm getting out of this is, anarchism is not the absence of social structure, but the absence of *formal, institutional* social structure. Have I got that bit right?
