You claim that common sense will produce certain economic results, however in most fields claims of "common sense" would be laughed away. Anyone who argued that we can know both the exact position and velocity of any particle would probably be regarded as having common sense less than 100 years ago. Unfortunately, common sense is not proof of any measurable claim.

In addition, you continue to ignore variables in favor of the ones you care about. Specifically, you argue that the savings would positively benefit very specific segments of funding and revenue for certain small businesses. Meanwhile, you completely ignore the effect that the taxes have on other variables, like infrastructure development. This is the same fallacy of Power that I proposed before.
