What has stopped anybody from doing this??
Well, they don't work for one thing.
Er... they work pretty well actually. The smaller ones don't make a lot of power, however as long as the wind is blowing, it's making at least a little juice to offset your bill. You need to make sure your area supports net-metering before you do anything else. The more wind, the more power, however you can get too much wind which could really screw up the unit unless it has a safety cut off to allow it to spin. They may have fixed all this in recent years, I don't know.
But yes, they do work.
ETA: The house I'm in has a small one and it produces about 7 or 8 kw/ on a good day. Not much, but it's tiny. It was here when we moved and I've never bothered to find out much about it. Landlord deals with it.
