What good are all those documents in regularly self-destabilizing countrys?

I never understood how you can claim to "own" something like land in some African crisis regions- where the "ownership" totally depends upon the current Regents poplar agenda and is heavily taxed with corruption & extortion.

Who invests into such monetary black holes?

Did you bother to look at the list of countries they work in before you made that comment?

Yes? Lots of south-american countrys (Argentina, Ecuador and Mexico), famous for swallowing helping money and producing geysers of extortion schemes and good intentions being used for as cover story for bad intentions.

Not as bad as some parts of africa though.
