I'm not sure I follow. The whole point of YIMBY is to increase the supply of housing such that new residents don't displace residents. If 10,000 people move into the city and move into 10,000 newly built apartments then no displacement needs to occur. Conversely, if NIMBYs block housing and 10,000 people move into the city with only 1,000 newly built apartments then 9,000 people are displaced. Sure, this is an oversimplification; people can live in converted living rooms, put bunk beds into 1BR apartments, etc. But the point remains YIMBYism helps prevent displacement, NIMBYism helps cause it.
