Because you have not provided any statistic or factual support for that little theory of yours.
It is nothing more then a personal opinion, that very few people in this Dash community place any value on.
LoL ! Are you serious ?
What is it about the phrase "we don't need all this hashrate" you don't understand ?
The protocol itself only requires 40% of the chain to be mined. You can switch it around philosophically anyway you like and say (for example) that the entire chain is mined, but then you've got to accept that the cost is borne disproportionally by investors in the primary supply (who finance the mining).
There is no escape and you're going to have to address that disparity because the market sees it and we have our fingers in our ears.
