I completely agree and have felt that way since shortly after 9-11. Anything built there is the single biggest target in nyc, so why make a new skyscraper that is as vulnerable as the first?

All the issues you raise are correct. Insurance will be insane - passed on the the consumer or taxpayer, of course.

Also, how do you secure the contrsuction site? The bad guys will simply not let anything like that be built on the site - time is on their side, not ours.
