Price as a function of time

Came across this repo while researching Harberger taxes and trying to get one implemented for BNS on the Stacks blockchain. I came up with a modified Harberger tax scheme that uses a price that is a function of time which can help address the issue of a whale or speculator snapping up your domain name while still keeping it affordable for the current owner.

I detailed my approach a bit more here: [https://github.com/stacksgov/sips/issues/118](https://github.com/stacksgov/sips/issues/118)

Curious as to what your thoughts are on this approach vs the one you've used of a depreciating license.

Start by reading this issue and the linked Stacks SIP #118, then compare the proposed time-based price with the repository's existing depreciating-license approach. The issue does not name implementation files, tests, or a settled acceptance criterion; the work is done only after the approach and scope are agreed and the resulting behavior is specified.
