I don't think this really addresses my concern, though. My concern is not that economic circumstances will be damaging to these communities. My concern is that any one individual gaining excessive wealth also gains de facto power. Agorists can live in their communities unbothered just fine... Until that powerful individual decides they want more and have the means to get it. Once they have the wealth, maybe they use it to get an army, and we know at least some subset of the population is happy to enlist. Maybe they start using it to peacefully coerce people into agreeing to things they wouldn't normally because the rich guy has too much control over things they need like raw materials or critical tools.
Ultimately, it seems to me to fail to account for bad actors. Human nature and basic game theory practically guarantee that we'll always have to contend with them. Any system destined for success must acknowledge that and have some mechanism to keep them in check. As average individuals, their capacity for harm is minimal and maybe not too important to address, but as wealth concentrates and their power grows, their capacity to harm the community grows exponentially.
