Without air and water life no worka.
P2P commerce is also essential.
Past human history is checkered with currency manipulation and conflict..
Enter a new element for humanity; trustless p2p currency, globally decentralized...
Something humanity has been craving since the dawn of human history.

Yes, i can understand that without air and water, life would not work but does it have any connection with bitcoins?
We can survive without bitcoins also as bitcoins only are a mean of financial transactions and that would not come under the basic utilities or basic requirements of the human nature.
