I think that the West was surprised by the calm reaction of the Russian banking system to the SWIFT disconnection (although it seems to be presented as an economic nuclear bomb). It turned out that the banking system of Russia is perhaps the most progressive in the world, without problems with legacy, mainframes, punched cards and cobols - flexible, manageable and easily customizable.

But the gas pipeline has a valve that can be easily closed. Of course, Qatar already has buyers for the entire volume of liquefied gas and investments are needed to increase gas production. But it also needs the political will to do so. Europe froze Russia's money, which she paid for gas supplies, that is, Europe actually received gas from Russia for free. Plus, Europe has very strict antitrust laws, and Gazprom has already been subject to its penalties, in particular, initially the contracts included a ban on the resale of Russian gas, on the abolition of which Germany is now making good money by supplying gas in reverse to Poland. It will be very difficult for Europe to find gas suppliers other than Russia, so it will have to save a lot and maybe even choose between production and heating of residential buildings next winter.
