I can see a Planet Steem where in we earn, purchase goods and services and live our lives through Steemit!

I can see that too....I envision this a self-contained ecosystem where the apps people develop on here fill most of the needs that people have. Of course, they will still have bills to pay but a lot of what is purchased online will be in a STEEM store (more like many of them).

By the way, you are here now...that makes you an early adopter....the masses are just starting to get wind of this...it will be a while before they get here in force.

Down the road, 500 SP will see like an enormous amount.
