For someone capable of producing giant walls of text to illustrate complex points, I find it odd that you're able to fall so flat on your face at the first logical hurdle.  Unless people are posting their addresses in public places, you'll have difficulty finding the actual person who has the coins.  Law enforcement can't do shit if there person who has the coins is in another jurisdiction.  There's no conceivable way you're ever going to force someone on the other side of the planet to give back "stolen" bitcoin unless they were directly involved in the theft and even then it would be incredibly difficult to do.  If you hide your private keys somewhere that no one can find it, there's no way to force anyone to surrender their cryptocurrency, stolen or otherwise.  The list of reasons why you're so monumentally wrong could go on for several pages.

There are several accounts on this forum that will likely find their way onto my ignore list at some point due to spouting incessant nonsense or outright FUD and you're running pretty high on the list right now.  Go cry wolf at the local looney asylum, or start talking sense, please.  I'm sure I'm not the only one getting tired of reading this shit.
