> Why would someone that wants to exploit other people leave a place that lets them exploit others?
Because we'll kick them out. I'm always up for doing things i don't particularly enjoy because there's value in them, but I certainly don't want to live with someone who treats me like a slave.
> you will need something more than good vibes to serve as incentives
Sure. But you'll probably concede that we live in a world run by psychopaths where children in schools are taught how to become psychopaths themselves. The first thing we teach children is "copying is cheating" and we're wondering why we're fucked? I'm not saying there's a time and place where everything will be perfect and we can all live happily ever after (i'm not a hippy), but there's very rational reasons for the ways everything around us is bad, and very rational courses of actions to fix those.
Abolishing property as State-mandated religion doesn't mean that some people won't have more than others (this would be ridiculous). But at least it would mean that nobody would sleep on the streets while there are empty homes, and nobody would starve while there is wasted food. Both ridiculous situations are the consequence of private property and require considerable amounts of force and resources to apply. It obviously is not working at scale, as we can see from environmental damage and previously-unimaginable levels of inequality.
