No, the consequence of increasing the block size is not related in any way to the money supply of Bitcoin. That argument has no merit.
Bitcoin's value is limited by small block size though. A large part of the value of BTC is the value of the total transactions done through it. Limiting the number of transactions will severely limit the price in in the long term. BTC will probably lose out to an alt coin if the transaction back log due to the small block size continues and is not resolved sooner rather than later.
