When arguing about societal/legal/political things that have anything to do with location, people frequently imply that there is no friction to picking where you live or moving. As if people are born into the world as adults and the first thing they do is pick from a list of every available home in the country in their price range, with infinite time and information to make their choice, and then they and their job and family and friends and possessions are all teleported there. And they can do this again as often as they want at any point. It's frankly nuts. "Uncharitable" and "oversimplified" are not really strong enough words for how dramatic the fallacy of "just live somewhere else" is.
