Conversely, all your examples also require individuals to make individual choices. Arguably, no systemic change has ever happened without individuals choosing to act.
Not really. Not if it's just a propaganda/awareness campaign. It would only matter if anti-industrial agriculturalists were organizing, defined as building resilient social-political structures which could change policy at increasingly large scales.

I don't even think that's arguable except in the case of natural disasters bringing down systems entirely. The individual choices that matter, for the disenfranchised with revolutionary ideas, are the choices and actions that build organizational power. And building power is extremely grueling work when money is neither the goal nor vehicle, so that's why we see so little of it. That's why I'm not currently doing it, for the time being.
