If the lease gets renewed at market value then there's no point in speculating about what that land might be worth in the farther future. It's a key difference from a system where all of the future value must be captured at once by a single owner.

Doesn't that just turn into a property tax of 1% per year, without a massive tax bill every 99 years? 99 years is long enough that there's going to be at least 2 owners, which means all sorts of strategizing required on how to plan for the renewal of the lease.
