Depends on which areas you're talking about specifically, but many major US airports did start that way. Lots of neighborhoods have grown into the flight paths, not the other way around.
Why don't we keep it that way and protect bigger industrial boundaries around airports? I don't know, but it doesn't seem very realistic; it's too much prime land to control. Commercially zoned areas in every major metropolitan area have been approached, crowded, re-zoned or overtaken by residential development.
