Actually, Bitcoin is being traced, that is why centralized exchange wanting KYC, and that is the reason ant blockchain analysis companies exist. Bitcoin natures are a pseudonym. Right now, we need to put some extra effort to gain full privacy and anonymous using currency. At least, until the technologies somehow 'significantly improved'.
In other hands, I'd agree with @mjglqw and @squatter, Thanks to decentralized and open sources nature of Bitcoin, the network and the system can't be manipulated with any centralized entities, but it comes to other problems, we are as a community would definitely lag behind if the adoption process is being slowed down and prohibited by government.
