In an experiment you not only measure, you also conduct an experiment. And in an economy every decision affects everyone to varying degree. Especially government's because only violent actors can reach those who would otherwise not be reachable. E.g. when I sell you my service, it does not greatly affect anyone except you. But when I start doing my service for you as a government agency, I suddenly affect everyone because I have to tax everyone and do that I have to create ten more agencies including IRS, police, SWAT etc.
