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.

I get your point about p2p, decentralization, and all other transactions that involves money, e-commerce and financial advantages, but comparing It to air and water is completely out of context. First thing comes to my mind after I read your post is the level of greed that taking over your whole body and soul. You are the kind of person who will trade nature over the latest and high technology without any hesitation.
Incase you forgot your history. People from the past 500 years or so live without a piece of money.
And what made you so sure that if in case that happens, it would still be bitcoin? A lot of things can change in very little time and the use of btc may be obsolete with fiat working with another kind of online currency. Too much bias on bitcoin or crypto in this. Bitcoin is necessary, but we can live without it.
