For anyone who think "oh this is just California's Proposition 13 but with a time limit"... not exactly. The tax rate in California is 1% of assessed value where assessed value can't grow more than 2% or the rate of inflation (whichever is lower). In this alternative system the base tax rate would be significantly higher. Ideally, high enough to capture the majority of the land's rental value at first. It also sets inflation as a floor while prop 13 has it or 2% as a ceiling.
