One of the reasons I'm a proponent of getting a Steem based economy going-- for art, music, services, products-- is to create a tangible reason for the existence of Steem (the token) that few of the other cryptos have.
From where I'm sitting, commerce is the best shot we have at getting to build an alternative economy of sorts. Cryptos... without "something" attached to their blockchains, have (to my way of thinking) no more value than small pieces of paper with pictures of Ben Franklin. It's just an illusion. But if I can actually buy a bag of beans with Steem? Then it suddenly develops a tangible reason for existing. Even if "our economy" is just an agreement between... I dunno, 1/2 million Steemians.
EXACTLY....
oh...and don't forget 3D printing (plans)
