As with most of these proposals it runs into the large problem of funding or partially funding blockchain development which then has no smooth path to being enacted by the witnesses. At least in this case the developers would get paid, but we're still looking at a system that primarily generates orphan code by funding the worker voters' priority without reconciling it with any anticipation of the witnesses' priority at time of implementation.

I feel like this needs to be solved somehow before investing in a system. Unfortunately I don't have any good ideas.

The non-blockchain-development parts of this seem like a reasonably good idea, and the people already here seem to be having a good discussion of where the money comes from that I don't really feel the need to add to.
