Can you elaborate more? When you say "checks and balances" do you mean explicit legal mechanisms or implicit mechanisms like Tiebout-style foot voting?

I'm thankful even for some pointers in what to search for.

One example is the effective prohibition on spraying pesticides by air, including drone. Drones allow lower pesticide use than current, legal practices
