I upvoted because I expect this to help with the peg. I also agree that it's a better way to spend rewards that were gained by "policing" as any stakeholder already has incentive to police the system without taking additional rewards that certain "policing" steemians (not necessarily whales but generally funded by them) are claiming to require as incentive.
The only problem with this I see is that it is not a long term solution. It will reduce the value of the short term gains from the abuse mainly due to the decrease in the value of SBD. But even when SBD is of lower value this abuse continues and reduces faith in the success of the network. In contrast to the funding that goes towards policing, at least this isn't a cost to the network, and so I applaud you for that. Unfortunately it's not a solution for the cost, only an alternative. I guess the hope would be that those with the SP to police the network would choose this alternative.
