At least until they decide to overturn an old decision. They do that usually many decades or even centuries later, and have done it very rarely. I doubt they will EVER overturn the right of the federal government to own property, since almost all property has started out owned by the federal government. Deciding that would destroy the title chain of most property in America! And they REALLY hate to make decisions that will impact the courts.

Likewise, I think almost every federal court is going to ignore all of this sovereign citizen nonsense because any recognition of their claims would create a mess in the court system.
