Yes! Value is so subjective eh. We are so used to corporations dictating the price and driving demand through marketing to our egos. We are notoriously horrible at falling for that kind of stuff and having no clue what the risks really are. But when we start to look after ourselves, our 'needs' are suddenly more clear and easier to work out. The want's tend to go by the wayside when we start getting real with life. Even with barter we have to be careful. Something that I have may not be worth much to me but may be life or death for you. Does that mean I want an arm or leg from you or do I give it to you instead?

That is where my character starts to show as greed would dictate I get as much as I can due to your situation, OR I express kindness and love by giving it too you as it does not 'cost' me anything.
