The answer to the universe and everything is 42.
Since we are human, imperfect, and not God, and only know half of everything, we should use half of 42.
Therefore, 21 million coins represents that half of the great work is done.  Wink

As a play on the ridiculousness of the legal age to drink alcohol being 21

Legal drinking age is 18 in many European countries.

21 million was not chosen, 21 million is the result of multiple other choices.

Initial block reward was 50BTC
1 block is made every 10 minutes
Block reward halves every 4 years

Those three choices lead to 21 million coins, after so many halvings the block reward eventually hits 0 and at that time the number of coins generated happens to be just under 21 million.

As a play on the ridiculousness of the legal age to drink alcohol being 21, while the legal age to sacrifice your life and finally becoming an adult is 18.

Terminated.
Because Satoshi thought that 21 million is ideal.
Who are we to say that it is not?

Why not 1 bitcoin…

Why not 1million or 100million bitcoins, why not 21 billion, or trillion?

Why not 14 million?
