If an "inspector" didn't find issues like that you had a bad inspector. Which many of them are. And they have escape clauses in their contracts disclaiming any liability for things they miss. That's not to say a good inspector will find every fault either. They don't tear walls open, and they don't have x-ray vision. They only inspect what they can see.
