IMHO, the gift economy relies on the understanding of 'the common'. There are shared resources of land, services like water, power supply, the internet, etc and their operations and expenses are shared. I share the responsibility for the highways with all but am able to 'gift' a ride to another in need. I agree that there is no one size fits all. It seems that the perception is that there is and it is greed. Anything else is perceived as weakness. That approach is not sustainable for our earth.
