Yes, I added similarly, but at first I guess I should have been more specific that we don't receive any material return for a material giving. The feedback part is how I see it, where we induce positive emotional states as a return for sharing. It's not something the other person gives us as a return, so that's more what I meant as something we get back from them. The feedback is self-induced. We give and induce happiness in ourselves. Nothing is required from the other person, although it can be to also stimulate our sense of well-being from sharing.
If we developed "free energy" and automation, that sharing factor would exponentially increase, as I see it. Scarcity is a reality based on the individualist need to provide for our own survival.
I had devised an alternative new way of living, where everyone in the community joins and agrees that we share water, food and shelter responsibilities. We work 1-4 days a month, and all the basics for living are taken care of. Then the rest of time can be spent working voluntarily for ourselves, for others, giving freely, or charging money for those things, but the basics for life would not be scarce anymore. I see food, water and shelter as the basis for establishing our freedom. In our world, we can't live off the land freely ourselves to provide for ourselves, so we are locked into economic survivability that removes degrees of freedom from life. In this new way, we all recognize the basic needs to establish freedom for all, and then further advancements are voluntarily engaged in.
