I think, Bitcoin is similar to WATER.
In the Nature, there is water in the clouds, not gold

Any opinions?

There is all kind of water but you are right, need for bitcoin is similar with thirst for water.
Water to nature is just like comparison of the benefit of water to the world and I think that is different from the comparison made of bitcoin because bitcoin is trying to fit in as optional payment system. Before bitcoin, there are other and many means of financial payment system but water has been in the beginning even at the time of creation.
In fact, I read in the bible that the world surface was covered with water before creation
