Interesting article. Maybe taxes on (some) capitals/property is (quite) equivalent to expiration. Money (value) accumulated that not contribute to development (probably) must be taxed, to enter it in the development cycle. But made it expiring seems a waste of value, decreasing it's value with time maybe is better, to avoid it, must be invested in something productive..
