The number of coins is not that relevant. Grin emits a billion nanogrin every second. IOTA uses MIOTA as a unit, but that is also one million IOTA. Some people similarly propose replacing BTC by mBTC, a milliBTC. It’s all arbitrary scaling. What’s important for fair distribution if everyone had to put in a similar effort in getting a coin. With ICO that’s clearly not the case. The creators can assign themselves arbitrary amounts. Similarly, instamines and dev taxes detract from fair distribution.
