Speculation is always a viable option early in the game but without the intrinsic value, all such schemes always end one and only one way. Crash :)
Yes, this just speeds the process. The only way it really can work is if there is actual creation of value somewhere along the line that feeds back into the system.
We are currently working on such a solution. We will see if we can improve on current model or not. I have listed all proposals and changes that will be implemented in this article if interested. https://steemit.com/photography/@bescouted.com/importance-of-token-economics-and-capturing-value-in-utility-tokens
