Demand for money is not infinite. In fact, there is no real demand for money at all, only demand for the things you can buy now or in the future for money. So you want the money to buy other things, not for the money itself. The closest thing to organic demand for money is the store of value trait of good money; you temporally arbitrage production changes relative to money supply hoping that that money can buy you the same or more value in the future, that's another dimension added but is still ultimately only demand for the things money can buy.

This means 2 things of course, one, that "demand for money" is ultimately only network effects (the set of all markets accepting a type of money is a network) and two, that "demand for money" and supply increase do not occur in lockstep, there's an interesting feedback loop there actually, but that demand follows supply increase relative to production increase.
