Nobody is going to confiscate Gold...and if they tried they would have to dig up half the state.

They did back in 1933. Now of course, not everyone turned theirs in. Why do you think that the 1933 double eagle is one of the most valuable coins on Earth? And all of those pre 1933 eagles and half eagles...well they obviously weren't turned in either. There are some that debate if owning a gold coin dated 1933 or earlier is even legal.
