Have you all seen this:
http://www.coindesk.com/roger-ver-denied-us-visa-attend-miami-bitcoin-conference/Why would the government do this other than to mess with him? Is it because of his connection to Bitcoin or because he renounced his citizenship? If you renounce your citizenship you can't go to the U.S. anymore? I suggest we all mail a cup of fresh urine to the U.S. senate in protest with a label that says, "piss off".
When you look at the laws regarding citizenship in the United States, you are only a citizen if one of three things fits your circumstances. These are:
1. You were born in the United States;
2. You were naturalized;
3. You said you are a citizen but you lied, and government accepted your lie.
That's about it. Maybe none of us are citizens. Maybe not even residents. Certainly not in our capacities as human beings. Maybe we as humans are only domiciled here.
There is question as to whether or not you were born in the United States, even if you were. Why? Simply because there are several definitions of the term "United States." The term is ambiguous, and you probably didn't understand - and don't understand now - the legalease (legal meanings of) regarding which "United States" you were talking about when you renounced your citizenship. Ambiguity is not allowed in law. Besides this, the definition that you would fall under when you were born is not the definition that applies to you when you are entering the country, and it is not the definition that you renounced when you renounced your citizenship.
In other words, when you present a passport or other documentation to port authorities, and they say, "This looks like you." And then they ask you, "Is this you?" What is your answer? You say, "Yes, it's me." What you have just done is turned yourself into a piece of paper, a passport, or some other documentation. And, since you are still a human being, the word "you" when they ask, "Is this you," is plural, meaning both you, the human, and you, the documentation.
Your answer should have been, "That is not me. I am a man/woman. As a man/woman born in the United States, I claim right of entry." Then, if they don't let you enter, you can file suit on the individual in his/her private capacity, who wouldn't let you enter.
Take a look at the info in the links listed at
https://bitcointalk.org/index.php?topic=916456.msg10079836#msg10079836, and see that government's determination of illegality about anything doesn't apply to you except if you are in government, or if you want it to. It becomes applicable to you when you say, "Yes, that's me," regarding some government documentation.
