You should certainly do what you want, but I HIGHLY suggest you DO NOT sign up for Obamacare until you read this CAREFULLY. Chief Justice Roberts carefully worded his ruling and left out any requirement to participate for 95% of Americans.
Even worse, courts have agreed that neither they, nor other government officials, have to tell you you're being treated as a corporation, under the interpretation that you don't need to be told, since you volunteered in the first place.
And that matters. Because by definition, the Chief Justice of the United States Supreme Court is not frivolous. Even by the interpretations of the IRS.
