Value stability is extremely important to a transaction medium.  Current value also correlates very closely with network hashrate and therefore network security.  If value continues to fall, vertcoin will end up the nscrypt crown holder, and exe will be left with with little to no hashrate (and therefore no network security, and therefore next to 0 utility).

And besides, cryptocoins have vastly more similarity to comodities then currencies.

We are talking about trying to stabilize value, because at this point it is crucial for network longevity.
