Would it have been that hard?

I am not an electrician. But I have done some electrical. In Florida you could do your own, and my inspectors encouraged me to do that. Most of it is not rocket science.

Using modern (as in the last 30 – 40 years) electrical cable, it is easy to ground a metal electrical device box. Of course, for a lazy electrician, it’s even easier to cut off the ground wire in the cable and leave the box and switch ungrounded. And unsafe. Ask me how I know they do it.
