If a non friendly transaction occurs then those unaccounted for shares don’t get covered but rather get “discovered” as not existing leaving investors with a potentially very big loss.

I can't imagine this to be the case. This would lay waste to the markets and faith in the stock exchanges. Imagine someone buying in good faith a publicly listed stock on an exchange, to suddenly discover that he holds toilet paper while the likes of Ken ride off into the sunset with billions of profit. There must be a system in place to protect innocent investors from such a calamity - some sort of industry insurance to protect against this.
