In the end I think that more than limiting Russia, at least Putin, what will do more harm will be to the people in general, because heads of state never cease to be well, with his sick mind, he will really continue to live opulently, he will not lack anything for himself or his family member.
Now, very probably he can exert pressure by limiting or eliminating the sale of Gas to Europe, there if I consider that it can damage, however, in the long term it would detract confidence to his government, because he has had gas contracts with many countries for decades, and if he fails to do that, fines could even come.
I believe that a great economic chaos could be generated, especially due to speculation in the large markets.
In fact, currently electricity and gas prices have risen a lot in Europe, as far as I know, and this will already have repercussions on the prices of many things at a global level.
An economic disaster is coming, indeed, if some measures are implemented where the poorest will be the most damaged.
