Let's say the residents of a small and poor town called Mena (just for example) agreed to create their own token, called Menacoin. And the community agreed that all stores and shops in Mena can use this Menacoin for any kind of transaction instead of just cash like dollars. And then this Menacoin distributed fairly to all residents of Mena.

So now imagine the power of the community: People in Mena can live their daily live without using a single dollar of cash. And because of the fair distribution of Menacoin, all the poor people can now enjoy the same tratments and the same privilege like everybody else in Mena.
