I think you misunderstand the Russian situation a little bit. Russia has not blocked the movement of cash - you can transfer out up to $50k per month to self or relative. Secondly, the cut off from SWIFT has meant that it takes longer to transfer rather than inability to transfer. Oligarchs don't need to transfer anything - frozen accounts are still accessible for personal expenditure so it's not like they are starving. Moving to crypto for business deals is obviously a non starter.
