As city residents go, I'm pretty trouble-free. I pay my property taxes. I recycle the garbage. The fire department visited only once, when a roast in my oven set off the smoke alarm. All in all, I've been a good deal for the city. But that doesn't mean the city couldn't do better by getting rid of me. It could level my house and tomato patch, and have Costco build a big box in their stead. Because Costcos take up a lot of room, the city would probably have to grab 15 of my neighbors' houses, as well. No problem....
