I cannot comment on the rights of a person in the EU against seizure of personal assets. In the United States there is a right to due process of law if the government wants to deprive citizens and some other classes of people (long conversation) of property (money or actual physical property) or freedom (jail). This can happen through legislative action and (sometimes) by the fiat of an government agency like the IRS, but when either of these happen people can get the matter heard in court. However, at times Due Process can be a fuzzy concept, like when property is seized as part of certain drug related or anti-terrorist laws. TL;DR: This type of taking would be harder to do in the US unless you are a terrorist of a drug dealer/smuggler/or in possession of drugs.
