ELI5: Why do bathroom stalls have gaps in the US?

I never really thought about it until I started travelling abroad. It's not like it'd be hard to build them better, or would it?

1) Easier to mop the floor.  Walls mean seams which can gather grime and other funny stuff.

2) Cheaper to build. The stalls mount at two points: the wall and the door pillars.

3) Less hanky-Panky goes on when the stalls aren't 100% private.
