Users don't care about the value of Steem, they care about the apps, and care about maybe getting paid in USD or Euro from the apps. As long as the blockchain is not abstracted people won't use the DApps. (Similarly, do you care about the value in games which add micro transactions via gems?).
Investors is what makes it look like a scam since they bring strong volatility.
some good points I ignored since i am maybe too long here lol!
I mean for the short term, investors is what we need if we want to sell off our Steem for a decent price. On the long term we want users and apps to sustain the eco system.
