That sounds cool. I don't know how familiar you are with Eve Online it's sort of built around these kinds of dynamics. For a while I made in-game money in Eve by conning my way into corps (their equivalent of guilds) and stealing ships from shared ship warehouses (I was a shitty teenager). The devs won't intervene unless you are exploiting broken mechanics in some way so my victims would pay other players to come after me to try to get me to pay them back. Eventually I ended up on a list of targets for some of the major corps and would just get immediately killed when I entered certain areas.
I will say I mostly played Eve as a teenager with nothing else to do and every attempt I made to get into it more casually later in life failed. Partially that's because, as cool as these dynamics are, it's very hard to participate in them meaningfully if you are not all-in on the game. I would be very interested to see an attempt at evoking something like this without all the baggage of a normal MMO though.
