In some countries, the weather is such that it is covered with snow all year round. If the gas supply in these countries is cut off, an unimaginable bad situation will arise. Countless people will die because of the weather in these countries.
In some countries, why don't you name a few?
It's quite funny when I hear people talking about Europe and thinking that in northern Europe it's snow all year long, we all ride sleds and it's like Frozen every single day. Might surprise you but there is no such thing anywhere, this is Oslo in summer:

Europe gets way less snow than the US, it gets in a lot of parts less snow than Jpana and in some parts, it barely snows as in much of France, UK and Spain.
So really, stop with these silly things.
In countries such as Germany, industries are being shut down due to unavailability of gas. And even at this point, pipeline gas (as per contractual terms) from Russia is manytimes cheaper when compared to imported LNG from Qatar or the United States.
And of course, you have no real proof of the "many times cheaper" thing as you claim.
Let's debunk this myth of LNG being x times more expensive, directly from the source:
https://www.aa.com.tr/en/energy/energy-diplomacy/us-lng-price-up-to-40-higher-than-russian-gas-novak/20225The price of liquefied natural gas (LNG) from the U.S. is at least 30-40 percent higher than Russian pipeline gas, Russia's Energy Minister Alexander Novak said on Saturday.According to Russian news agency Tass, Novak said that the U.S. wants Europe to buy its LNG but the price of which is at least 30-40 percent higher than Russia's piped gas.
So before all these events even Russia barely manages to claim its gas is 40% cheaper than LNG.
