Lets face it 90% of the word does not know who he is, no one outside of the deluded left would give a fuck if he was taken down yet there is no more outside of Russia to take him down.
It makes no sense, when it comes to the disrupting in the USA, politicians, judges, AG's, NGO's, protest groups etc, all roads lead to this germ and yet?????
The idea is to make sure that there are enough layers in the system so no wrongdoings can ever be traced all the way back to you.
For instance, if you want to donate many $millions to a certain organisation you do not simply write them a cheque. Rather you create some NGOs, foundations, trusts, charities etc. Then you donate money to them. They may well give that money to the people you really wanted to donate it to but, obviously, that is not your fault.
Any behind the scenes discussions between representatives of the oligarch and representatives of the foundation are kept behind the scenes.
