The fact that some profits will be used to provide a support level on the market does not increase ICN's value. People wanting to possess ICN is what would increase its value.
Your statements make no sense.
Profits are used to provide
support level - this what makes people wanting to possess ICN, this what creates value.
Otherwise it can be said that none of blue chip companies that don't pay dividends but rather do buybacks have any value whatsoever.
Also what you are saying is that GOOGL is as worthless as MEND
Like it or not, business and economy in general are built on trust. The majority believes ICN is the true token that represents Iconomi, not MEND or any other.
I am sure that in the nearest future Iconomi will move on to Aragon network or a similar project to give token holders voting rights and transparency. We are at such an early stage of crypto-world development.
Also from your statement ETH has value because
ETH is required to use the platform, to pay for gas
(your other two points are the same as for ICN).
So... I guess I can use Google without owning GOOGL.... Now prove me it has no value.
And before you say about voting rights - one can also buy a class C GOOG. 
BTW, it's not quite appropriate to compare ETH to ICN. It's like comparing USD to AAPL - different asset classes with different usage and purpose.
