^^^ The old Federal Building is a loss because of the materials and craftsmanship which are unlikely to be replaced any time soon.

Stuff like the Stock Exchange, Garrick Theater, etc etc is where you have a loss that transcends those physical characteristics and enters a realm of the philosophical or spiritual. The old Federal Building did NOT come anywhere near that.

In other words there is a difference between demolishing a prairie style bungalow and demolishing Robie House...
