The problem with your policy proposals is that you are assuming an economy in a vacuum. Neoclassical economic models represent a frictionless economy where everything is perfect. The are the equivalent of an upper bound for a converging series. When people tell themselves that the real economy is already hitting the upper bound automatically (this is an unfounded assumption, if you go this far then almost all conclusions are in your assumption to begin with), then absolutely nothing can be done to improve it so we should get rid of all that pointless nonsense.

If the real world does not live up to this idealized image, then some policies may have surprisingly positive effects and getting rid of them actually ends up making everything worse.
