1) Because you still have to deal with a rotting sector of abandoned and delapidated buildings and a bunch of asphalt you left behind. Not only will it look like crap (even worse than today) but it will breed crime that I will have to pay for more police and or sherrif patrol.
2) Because you have to knock down trees and cover a bunch of new land with asphalt
And you have no problem with this?
By this logic downtown Orlando shouldn't put new condos where old abandoned buildings stood, but rather just leave the old downtown to rot and try to start a new downtown elsewhere. Hey, this gives Parramore room to grow. Maybe Parramore should be abandoned too and we could clear some land and see who we could get to move there. We would also have a big rat-infested, crime-ridden CBD to be proud of.
It is my money and I wouldn't want to support a policy where whenever something gets old, you just move on, leaving a trail of asphalt and abandoned buildings in the wake.
I see why you are such a Crotty fan.
