The idea is more like russia is sending the message "we are suicidal and ready to do really expensive, stupid stuff, maybe even go nuclear, are you too?"
You're getting downvotes but this is why. Putin wants to end relations with western nations because democratic ideas are becoming more popular in Russia (and Ukraine, whom russians can easily compare themselves to, starting to prosper as a result) and that is a huge danger to his authoritarian legacy and to him. His ego is that Russia has superior culture and genetics when compared to the west and his losing to Ukrainians and NATO supplied weapons is really hard on his ego and reputation which is everything to him.
If only there was another pipeline right next to Russian armed forces that they could more easily blow up.
That would not signal readiness to do really expensive things.
Yes, Russia is not prepared to do expensive things in the middle of a billion dollar a day invasion.
