Putin leaving like Yeltsin left might be ideal only for the possibility it were less bloody then him clinging on to assets and power like other authoritarian regimes. If possible a trade could be made when the cronies and kleptocats were too old and feeble to realistically maintain power much longer that they would release power and transition peaceful into a real democracy. Reminiscent of the transition from the USSR to modern russia but even more progressive than the 90's
