The problem is that many people in Ukraine are on Russia’s side and most others would abhor the approach you advocate.

What you’re suggesting is not realistic and would be counter productive. If some elements(presumably the most extreme nationalists) were to to try this, it would play into Russia’s hand.

Bleeding the enemy in a way that takes away their cash to invade isn't the worst.
Based on what you are saying, if that happened to us we should take it?
If we don't take that, then why should they or why are we not doing anything beyond suggesting they be a cooperative victim?
