First of all, it's not a "theory" so the concept of "proof" doesn't come into it. It's a statement of the self evident - that the role of mining is to put a price on the acquisition of a coin from the continuous supply.
Back up a bit... the main point of this discussion is regarding DASH's reward ratio and how according to you it's directly causing DASH's fall in the CMC ranks. I haven't been discussing the role of mining...
I've always maintained there's some merit to it but that you overstate it.
So what was the point of addressing it in the first place then ? It's the single biggest protocol revision to mining since the early days of Dash. It's also a statement of priorities for both the community and the core group going forward. You don't think there are serious implications of getting this wrong to the extent that the logic is actually reversed ? How on earth can that be overstated when Dash's entire competitive offering has always been promoted based on features and we can't even compete with coins that have none ?
Yes, you overstate the problem since it currently amounts to you getting about 0.03 DASH more per payout. Is this the straw that broke the camel's back?
If we don't need the mining why is our mining deficiency killing us and their mining sufficiency boosting them ?
Did DASH somehow lose mining? And again, you ask a question based on a dubious premise...
