Earlier quoted context omitted.
Europe has some gas reserves. We could "see out winter if Russian imports stop" [0]. I personally don't mind wearing an extra sweater or jacket inside if it stops Europe from paying billions to Gazprom. > While a complete loss of Russian gas imports, currently making up almost half of Germany’s gas needs, “will lead to bottlenecks in some European countries”, supply shortages “would be limited to up to 10% of demand”…
You don't mind wearing a sweater but I'm willing to bet you're not elderly, nor poor, nor living in substandard housing. Any of those would make your sacrifice simply one more example of an action that hurts the most vulnerable in society while claiming to be a good thing.
Elderly and poor will be hurt the most, that is true. If the source I linked to is correct, it claims it would only impact 10% of demand. While I don't know what that would look like in practice. I sincerely hope (and expect) that it would not lead to anyone, including the vulnerable, freezing to death, or getting seriously ill.
