There is no free will. Your actions, thoughts and ideas are limited to the experiences and environment you have developed in. You will continue your actions until you experience the consequences of them. That is why our main focus as an movement is making people aware that there are alternatives and that we can choose a better way of life. Our model has nothing in common with historical failed experiments in social control.
Never minds if there's free will or not for this case. I agree with you in that: if you accept determinism there's no such thing as free will. But when we talk about freedom we just mean the opposite of social control.
What we can't understand is how you disable people from wasting resources without any kind of money nor social control/planned economy.
Just with education?
Ok, but that's not new: Jesus also believed that education was enough to achieve social harmony.
Are you that innocent?
