Maybe there would be a way to cohesively integrate witness rewards into the proposal and steem rewards economy. Witness rewards were always an incentive to for the infrastructure donation that witness have to make just to be witnesses on the blockchain. Maybe those rewards could serve more than one purpose that can be used to offset inflation.

It could possibly address the stale voting issue of witness votes by replacing the top X witness system with rewarding witnesses through funding appropriations instead. Without getting too specific, witnesses would be rewarded through successful projects that they fund through steemit appropriations. This would basically turn witnesses into angels. The more projects you lead to success, the better witness you are, and the more you will be rewarded.
