it will save trees..

my friend just read in a mag that they may be getting rid of physical money; coins and bills, as in. so all we'd have is credit and debit cards. this really freaked me out, and i cant explain why. maybe because it would be that our society will be ruled by this imaginary thing. just a bunch of numbers on a screen or a receipt. if something is as important and neccesary as money, i would like to be able to physicaly see and touch it. i have no trust in imaginary concepts.
