Anarchists, rioters and the like have a severe lack of imagination, which stems from most actions being unplanned riots responding to outside stimuli. Within the rioting can be a feeling of camaraderie, adrenaline and opportunism. I’m suggesting a focus on long-term, planned, more targeted, lesser assaults on capitalism.
For example, going into a KFC with a cage of baby chicks can create a lot of attention, and is barely a crime if you move on when the police arrive. You could argue that you needed to sit down for a bit because you felt faint.
Leaving human faeces in strategic locations can be a powerful statement that puts people off that particular business or institution. And not something you need to stay around for and get arrested.
Actions can be undertaken where nobody else is around. Machines and systems can be sabotaged in ways they do not expect. For example, rendering payphones useless won’t affect society much, but it will really piss off the providers, and cost them profits.
While I will never advocate the intended harm of any humans, outbreaks can happen to livestock and crops. Fires happen and dams sometimes release water. Products for human consumption can be made unpalatable without causing harm.
When all of civilization can be the target, and enough true believers make enough small actions, that could be enough to send economies into recessions, and make it unpalatable to bring more children into this world.
Consider also the flow on effects. How many times can a business suffer insured damages before the insurer no longer wants them as a customer? How many actions happening all at once, stretch the police too much? How much disruption is enough to put off tourists from arriving with all of their GDP?
