Nice rundown, I appreciate it. Also noted Austria made the list (surprised) but Luxembourg & Liechtenstein didn’t (more surprised). I don’t know much about the subject though and at this point I’m sold on holding physical gold (no larger than .25 ounce coins) or junk silver. The idea is hiding assets from means testing and also avoiding estate taxes.
As noted, each person has different goals, which is the main reason why the question is very difficult to answer in the general case.
