It doesn't work that way. The regulations are being aimed at "virtual currency." You would just be trading one virtual currency for another one. As the regulatory engine ramps up to full speed the legislation passed will become more all encompassing eventually crushing all forms of competition.
ill paste you this you may have read it already.
https://bitcointalksearch.org/topic/m.2574555bitcoin is not owned by any country so bitcoin cant be regulated by a country at the moment. the only thing that can be regulated are the FIAT exchanges and the businesses that hold digital forms of dollars on a database that represent the actual FIAT in a bank account EG bitstamp/mtgox.
on the trading floor you are not playing with bank account FIAT (real currency in fincens eyes) you are playing with digitial fiat (convertible virtual currency in fincens eyes).
i do not want fincen regulating bitcoin itself. i do not mind them however regulating the people playing with FIAT. and i have at many times facepalmed teentrepreneurs (teenage entrepreneurs) who play with fiat but feel they dont need licences purely because they class themselves as a bitcoin business.
bitcoin is its own country, its own economy. not one other country can claim it is their property to then regulate it. the most they can do is make it illegal to obtain, which would drag bitcoin more underground and cause more problems for them.
i prefer people to individually have a moral compass, to do their own due diligence on who they trade with and decline trading with anyone that sounds shady. rather then having a government control bitcoin for their own purposes and freezing assets without warning.
that way when my american friends come to me and say they are low on cash, i can pay them a wage or give them some donated bitcoin so they can buy a nice pizza on foodler the same night. without all the regulatory paperwork, bureaucratic nightmare of 2-5 delay in transferring 'real currency'.
bitcoins number one selling point is that it is it's own economy away from government ownership and control. any future regulations brought in by gavin allowing american government to decide changes to bitcoin-QT updates that auto tax or freeze public addresses would ruin bitcoin and make bitcoin property of the US government. which then ruins all of the appeal of bitcoin for people in europe, asia, england. that want to trade with americans, just without the bureaucratic nightmare
