How much is oxygen to dollars?

As a cryptocurrency and finance professional, I'm often asked questions that require a unique blend of technical and conceptual understanding. Today, however, I'm faced with a rather unusual inquiry: 'How much is oxygen to dollars?' This query, while seemingly out of the ordinary, actually begs for a deeper discussion on the valuation of necessities versus commodities. Oxygen, a vital element for human life, is often taken for granted and its value not measured in monetary terms. Yet, if we were to consider its scarcity in certain environments or the cost of producing it in extreme conditions, how would we translate that into a dollar figure? This question challenges us to consider the fundamental relationship between life's necessities and the economic system we've constructed.
