Doing Minecraft a unique world

Attention this is not a bug is a proposal. I've written this in the bug tracker because I didn't find a web for writing proposals. My proposal is to making Minecraft a unique world, I mean that ALL Minecrafters could be connected in one world without connecting to LAN. It can be good, 'cause people could make a group and build towns together. But that would mean something. Creative mode should be deleted, imagine players killing others with creative, would be a chaos.

I think that this is a good proposal, if there are lots of votes in this proposal, please, apply it to Minecraft.
