Normal inspectors don't punch holes in the wall. Your inspector's job is to notice leaks in visible pipes and to use a moisture sensor to look for wet drywall. Read over your inspection report carefully. If the inspector didn't do a moisture test, that might give you a reason to be annoyed.

Meanwhile, since it looks like you're stuck redoing your plumbing, I'd encourage you to check out PEX pipes. Basically, they run flexible rubber tubing everywhere rather than rigid copper/plastic pipes. It's a star-shaped topology as well, meaning you get a central location where you can turn any outlet on and off. Among other benefits, you have more resistance against freezing damage, you avoid "water hammer", etc.
