At that scale it isn’t the money, it is the risk of damage to the surrounding area, which raises the risk of those falling and on down the line. The other buildings in that size range that have been successfully imploded are in places like a low density waterfront part of Abu Dhabi , a barrier island in South Padre Texas. The last thing somewhat comparable implosion in a more dense urban neighborhood was the old Hudson building in Detroit, which, while 200 feet shorter still ended up doing serious damage to public transit and minor damage to a bunch of buildings, while also filling something like a 1/3 mile radius of downtown with concrete dust.
