I think you are onto something, and the nice thing about this is that it provides a runway to move us to a basic income economy.  Eventually (30, 50, 100 years from now) all property will be intellectual because anything will be 3D printable, biological agents will be synthesizable etc etc so this would allow everyone to benefit and still reward innovation.<p>Also, a flat tax favors the wealthy on a linear scale but is fairer on a logarithmic scale.  So for example when income increases by 10 times, the corresponding tax rate could go up by 10% or something to that effect.
