I disagree. This is war - it's not meant to be comfortable - and a government does represent the people. Putin's approval rating over the years has been really high, in the mid-high 70s [1]. The only way this ends with minimal bloodshed is if the populace exerts sufficient pressure against leadership. That means protests, that means civil disobedience.
If the populace doesn't feel the impact of the war, then there's no pressure for the administration to end it.
Think of it more like less-lethal weapons. Yah you don't want to get hit by a rubber bullet but you certainly don't want to get hit by a real bullet. If things escalate then the people may get hit by real bullets metaphorically and literally.
[edit] > Punishing civilians for the actions of its government is absolutely insane and will backfire badly.
This is an interesting argument, especially for a representative government.
"You can't blame me for what the people I pick do!"
I mean, yes? I can? Even in countries without, governments can be overturned internally.[1] https://www.statista.com/statistics/896181/putin-approval-ra...
