Maybe we wouldn't get this far with Bitcoin and who knows if it would stick around, but anyway I think you should just call Bitcoin as however you see it in your eyes as everyone uses it differently and has their own opinion on it.
Satoshi tried to make a decentralized form of money, but you can't control free market price. This is not something Satoshi could have predicted.
He wanted people to use bitcoin the way they want and that's what happened, so I doubt that he'd be disappointed by the way things have turned out.
Bitcoin has a number of features and characteristics. If someone says it can be only money and a payment system, but not a store of value, or an investment, he makes no sense to me.
