Russia is a country with a strong centralized government capable of enforcing laws whenever it wants.
In the absence of effective laws, one of the biggest threats to rich people would be their own hired thugs. If the thugs decide that they don't respect you and they would make better rich assholes, they will kill you and take your property. Historically, societies like that were often ruled by the biggest and the most charismatic thugs, who could command the respect of lesser thugs. Or warrior nobility, if you want a fancier term. Today's billionaire nerds would not be among those.
