That's right, but Ukraine got $90B from Europe knowing most of it would come back for equipment purchases. Also - I think that EU is going to try to figure out a way to get that Russian money.

If they can't, then the EU should not exist - literally. It's decisive evidence that the bureaucracy can't even face an existential threat on it's own existence because it can't organize it's own legal concerns.

"We remained lawfully committed to juducial integrity and processes ... as we were exterminated!"

This situation is similar to 'many other things' (capital markets, tech investment, border/migration concerns etc.)

confiscating money is much bigger deal than you can imagine. Russia and the EU are not officially at war and just taking money because you can is a serious violation of fundamental rights.
