After all, the only protection that would actually protect would be

All this plastic/thin metal tacky stuff won't protect against an
electric drill.

It depends on the type of bit. I think thin metal or certain plastics might protect against a masonry bit, which is what someone would be using to drill into the wall. Masonry bits are not sharp.

I once drilled into a wall and found I reached a point where I could drill no further. I tried drilling for a long time getting nowhere and finally discovered there was a cable there behind a thin metal strip.
