I disagree with you
Wait, about what? Are you saying that shooting people in the head is more effective in dealing with climate change that blowing up oil pipelines?
I think if we stop using oil hundreds of millions will starve in days
I agree with this, and I never said we should stop using oil. I think we should definitely use less though. We should try to use as little as possible. We will still need plastics for medical stuff.
Just don’t use violence because you don’t have a monopoly on it, we all can do it.
A lot of people are about to die due to climate change. I think if you want them to not do violence, you had better start convincing them that they have a shot to survive this. Telling them that violence is bad is not going to do it. Honestly, blowing up a few pipes is pretty low price, all things considered. Things have the possibility to get much worse than some property damage.
I would 100% prefer that governments take action to slow down oil production and push hard for more climate friendly policies, but they are not.
If your political system uses wealth as a means to create policy. Then whatever economic system you use becomes political.
