The buildings to replace the WTC-complex are not important for memorial purposes. The iconic power of commemorations like the Tribute in Light are. The Germans have a word that translates as "places to throw wreaths" for memorials with no soul. Rebuild lower Manhatten as a living city, concentrate on that. But bid every year in September the Ghosts of the WTC return, as the Tribute in Light or in other forms of cutting edge technolgy or brute-force engineering. Let them revisit the City and Nation annually and yet fade away into memory til next year until the pain fades too.... Let the Ghosts come but once a year in reproche' for all that we still have to do, and a time will come when we'll say as a Nation "it's time to let go." As we have other wounds and traumas, as we have either forgiven or at-least accepted, old aversaries when we gather.
The Ghosts don't live in a hole in the ground, they live high over our heads in the clouds.
