Part of me wants to know what life would be like for a SovCit if their whish came through:
No more obligations and dealings with the US government or any affiliated services, at all.

No more taxes. No more utilities. No more access to a landline, ISP or mobile data.
No post address, no social security number, no bank account.
Banned from using all public roads and entering all public buildings.
No legal protection for their property, no constitutional rights.

In earlier times, that was called "outlaw" and was the harshest punishment available, usually equaling a death sentence.
