You need a Nash equilibrium for security aspects, but you also need one for adoption. If someone premines the entire coin and has the market cornered by design on day one, there's zero incentive for anyone to adopt it when the issuer and his cronies have such advantage over everyone else. You're just replicating central banking except the value of central banking units is derived through coercion, and without it, it would have no value.
Which is precisely why it can't become a "value transfer system" where that is supposed to mean a currency and unit-of-exchange, and not a transfer of value from gamblers and fools to
snakeoiltechnocoolbabble salesmen.
