As far as I have read David Irvine vision is for Safcoin to serve for storage allocation token on the Safe Network. That a Safecoin could possibly become something more than that, i.e. serve as a unit of account (currency), is outside this scope and far from a certainty. A coin that is not divisible (and vice versa) is not a coin that can be used as a unit of account, and unlikely to be used as a currency. Hopefully it will be addressed but so far I have seen nothing concrete on this from the developers. @happybeing mentioned that there may be a fixed exchange system between different “alt-Safecoins” to simulate division over on this thread - it might work perfectly, especially if it is bi-directional and transparent.
Don’t get me wrong I would love to see Safecoin become a unit of account and not just serve as a hard drive space resource allocation token - which is why I keep pursuing this division question. I am just pointing out that given the current information any future Safecoin valuation predictions are hardly slam dunks there are a lot of big unknowns.
