A better comparison would be getting to vote in state elections. I can't vote in Florida or Kansas or Oregon. But when it comes to something affecting the whole I get to vote and so do those in Florida or Kansas or Oregon. This game is the whole, so even though we are separated for the majority of game interaction, the marketplace and possibility of more interaction affects the whole.
I have 1757 players for sale and I'm $25,835,360 in debt. Buy them at outrageous prices, or be selfish and make me go bankrupt. You decide, BB.
