There is no bill yet because they havent decided on an approach yet. Most experts believe the will go the "Capital Gains route" but that has yet to be determined.
So what you're saying is that there aren't any actual US regulations yet, and there aren't even any in the official pipeline. You're
anticipating regulations at some point in the future, and blaming "liberals" for creating them, despite the fact that none actually exist. If and when those regulations
do exist, you're expecting the regulations to take the form of a capital gains tax -- much like any other security that individuals might trade for profit -- rather than some prohibition on the actual trade of BTC.
Is that the gist of what you're trying to say?
