Total supply is completely arbitrary and meaningless as far as value impact is concerned. Value is influenced by changes in supply.
Let's build up an understanding of the supply curve. Supply vs. quantity supplied

Now let's tie it together with inelasticity. Scroll down to 'perfectly inelastic supply'
http://www.economicshelp.org/concepts/inelastic-supply/

With a fixed supply that has a perfectly inelastic supply curve, there are no changes in supply to influence prices from the supply side. In other words, at all prices supply will remain the same. Additionally, the total supply (location on the X axis) is unchangeable, so the curve will not shift in relation to the demand curve, which WOULD impact prices in the future.

EDIT: I don't want to risk being ambiguous here: The supply of IOTAs is forever fixed at 2,779 Ti. That makes it perfectly inelastic while also being fixed in place on the X axis.



Hopefully enough to be fully incentivized for project success. Considering that no token allotment was held for the devs or founders and 100% of the tokens were distributed in the crowdsale, the more he has, the more it cost him. Incentive alignment from the top down is important, so the community has donated an unprecedented amount of money to the IOTA Foundation and various other fundraising efforts.
