Aside from not being ideal from the Olympic Committee's point of view, it would leave us saddled with a lot of debt, and facilities that we would have a hard time repurposing. Just Google "abandoned Olympic venues" and get a look at all the decay around the world in former Olympic cities. We have enough problems puzzling over what to do with the Astrodome. Imagine having venues like that all over town that we don't want to tear down and "waste", but can't figure out what to do with. No thanks!
