Why do unpowered buildings still have to take up precious job space?

im trying to plan out computer production and a ton of other stuff isnt running efficiently just because these are connected to roads, cant there be a way to pause an area so i can plan stuff out without it wrecking everything else, and yeah i could build more housing but im putting that off for to do other stuff.

ok

Try pressing the space bar. It pauses the game

thats not the point, im building it and planning it out while also waiting on my housing to upgrade and my research to continue and while trying to stock up on steel, why tf would i pause the game? im trying to solve an issue of not having enough workers because of idle unconnected buildings getting filled with workers unnecessarily, not whatever it is youre thinking
