And would gladly work on a project like this to kill the time.

It's not a "project" it's a way of life, and it's not something you should ever engage in to "kill time" but because you believ it is possible to create a better society.

I worry that they’ll just roll over us with their tanks and drones unless the oligarchy is actually destroyed in the revolution.

They are going to do that at some point anyway, your options are to lie down and take it, or to try and create an alternative (yes, abolishing the current systems that control our lives will require violence, a tiny percentage of that they inflict on us, but you don't free yourself from oppression by asking nicely).

And I just don’t see how that can happen with the majority of people looking left or right instead of up.

That's the whole entire point of building community and solidarity.
