Need a City quant PhD to invent a mathematical analog of Black-Scholes [1] for pricing and trading the irreplaceable value of culturally significant physical spaces to future generations. Then City-like [2] institutions can compete financially for ongoing preservation rights, rather than a one-time chop shop auction.

"Preserving the irreplaceable value of ..." works great as a personal motivation or a mission statement, but terribly as an explicit rule. It's the same problem as carbon offsets - if there's a formula for converting intangible values into cold hard cash, people will exploit the definition of the intangibles to make money.

This is a gamblers ruin problem action.
