It's true that Bitcoin empowers people that want to stay hidden from the government's view.  The technology seems sound enough that this will be true no matter what additional costs governments impose on using Bitcoins.

The force that drives that empowerment is Bitcoin's ability to substantially reduce transaction costs.  This is a force that can also increase the wealth of anyone that chooses to transact in compliance with government.  Focusing on this fact is more honest to what the technology really is.  If governments don't act to impose additional costs onto Bitcoin, then everyone - governments, citizens, and the rare anarchist - will benefit.
