Regarding your suggestion the U.S. and the European Union nations go after assets of wealthy Russian citizens, this should never be on the table. Whoever these "oligarchs" may be, they are not the ones causing trouble in Ukraine, they're looking for a place to spend money. If some Russian oligarch chooses to purchase a condominium at Scarlett Place (my building) and invests millions for improvement, what right does the U.S. government or any other nation have in seizing the property? And if Western governments appropriate private property of Russian citizens, how will these possessions be administered? Think about it.
