It's hilarious what anyone want reduce block reward and coin supply. BECAUSE PRICE GOES DOWN.
Price goes down because where is no any real value in this coins, you can't buy anything real for this coins.
Block reduction mean only what miners (only one type of people who make decision put some recourse in this coin) will have much less reason to do it.
Without miners no one (except you who hold this numbers in wallets an waiting 'the MOON') will be interested in higher prices.
Interesting discussion... one of the reasons around the original total # of coins was to provide a base of liquidity to the system because of phase ][ we need coins in the marketplace... so its a mix of too much/too little or just right :-)
