Would that mean that if something was not continually growing in value you'd end up paying the value of it in taxes over some amount of years? Does this encourage people to pay the tax value out of the asset or just divest from non appreciating assets? If you paid taxes from the value of the asset I guess it'd be like a series converging to zero over time? Like 6% of 100 is 6, the 6% of 94 is 5.64, 6% of 88.36, vs. paying 6 bucks every year. Slower but sort of an eroding effect - like paying society's subscription fee for how you got the value in the first place!
