The discussion "money or not" is shallow at best and I'd more like to look on the actual effects of our actions. As an example, I will take on of the current debates:

How should we get a WuppHouse?

First we should define an objective, the ultimate goal: what do we want to achieve? This is a very open process, sometimes called dreaming. For the WuppHouse case, there's a list of dreams.

Then we should find out more about our values: how do we want to achieve it? What price (figuratively) do we want to pay? What price do we want to make society/nature/future children pay? This is where the compromise starts. Some values conflict with each other, and it's up to the group to identify this upfront. Coming back to the WuppHouse, these personal experiences are starting point for, but a more refined writeup is wishful.

Then, a continuous cycle of planning and doing starts. It's always worth considering if the values are kept and the goal is coming closer.
