> Why aren't we building airports with enough space for a plane to remain on the ground and have plenty of room to decelerate in this situation?

But that's exactly what a runway is? They're extremely long, have ample safety margins, and have "protected areas" extending out on either end, and outside of that there are regulations about what can and can't be built along the extendend runway centerlines. But jetliners are huge, heavy, fast, and designed to go long distances - the stopping distance of a fully loaded jet at full takeoff speed is measured in miles.
