Yeah seems weird to just be able to seize an 'individuals' stuff.
I was at university Phd in politics when Soviet system collapsed. The permanently drunk Yeltsin, accepting capitalism, had 12 blokes hanging round, Abramovich one of them and the whole of Russias assets was carved up between them. So those assets are inextricably linked to the Russian state. He also made an ex KGB agent Putin in charge of the country.
