Around one million coconuts required to fly from Tokyo to Los Angeles.

Around 40 million flights per year.

40 trillion coconuts required for all flights, or 1000x current production.

To scale up coconut production we need 12 billion hectares, or 80% of the Earth's surface for coconut trees.

We need 100k cubic km of water per year, or twice the renewable fresh water on this planet.

Ok cool. We will need to terraform Mars before we can fly by coconut.

Finally I understand the mad billionaire's plan.
