I don't think rewarding certain behaviors like sponsoring is good, because its too easily abused. When a KPI becomes a target, its no longer a KPI.
There are probably 2 or 3 orders of magnitude too many laws currently in America (have you ever estimated trying to read and comprehend the entire law? Borderline impossible in a single lifetime even under very optimistic reading-speed assumptions etc).
If this metric becomes a target and ceases to be a good metric, that sounds ideal because it'll have the side effect of drastically simplifying the legal code.
To be blunt, your whole polemic reads like a CATO fever dream, which is the opposite of what I was suggesting; ideological contrivance isn't a solve, and complexity at a nation our size and scope ain't gonna get reduced to a nice pamphlet of rules. It's the same reason you can't run a FAANG company the same way you run a 6 person A-round company.
Bonuses and promotions always go to those who exceed them, and "improvement plans" or "restructuring" is reserved to those who miss.
Any imperfect measure that becomes a target gets pursued at the expense of the original intent.
