He has come up with that number for the conclusion of making it scarce. Just like what the content of his email to Mike Hearn that says this;
Great share Cool

I fudged it to 364.58333 days/year. The halving of 50 BTC to 25 BTC is after 210000 blocks or around 3.9954 years, which is approximate anyway based on the retargeting mechanism's best effort.

I thought about 100 BTC and 42 million, but 42 million seemed high.

I wanted typical amounts to be in a familiar range. If you're tossing around 100000 units, it doesn't feel scarce. The brain is better able to work with numbers from 0.01 to 1000.

If it gets really big, the decimal can move two places and cents become the new coins.

It's not as exact of what he's said but if we're going to analyze what he's said, it's all about the adjustment through the blocks mined and that leads to the main thing which is about the scarcity. Everyone can read the entire email on that link on the quote.

To add about the answer of "if it can be changed" - for as long as the network remains secure and in tact, the supply can never be changed. If it is ever changed, that's a big fundamental shift for Bitcoin and a lot of its holders will likely divest, as its fixed supply is one of the (many) primary reasons for the value that it has today.
