>like all the west should have stronger actions and isolate russia on different levels, most importantly isolate the economy and flatten it the ground, it is possible to do but there is always a cost for that. But it is the least it can be done if military intervention is not on the table.
Russia would not have pursued this invasion if they weren't confident that they had an answer to that in the form of China.
That's not to say that sanctions wouldn't have a huge impact, but not to the degree that you're hoping. And the effect of sanctions becomes weaker every time they're used, as the target market will find alternative paths.
