We're trying to create a brand new currency here, without bootstrapping it off an existing measure of value.  This has happened very rarely throughout history, and the odds are vastly against us being successful with even one.  What this requires is widespread adoption and trading depth such that volatility is sufficiently smoothed out, and the currency is usable for accounting with.

Convincing those that don't understand this to spread their value among multiple cryptocurrencies meant for the exact same purpose so obviously goes against the goal of gaining sufficient trading depth of one.
