Well this is quite alarming given that Bitcoin has been made or invented in order to have free transactions. And by free transactions I mean transactions that are not traceable and not attached to any personal information. If Bitcoin ownership will exist and no longer through addresses, than the whole Bitcoin idea in the first place was already gone. Next thing we know it may be regulated by a government too.
Bitcoin was never intended to be untraceable. This is one of the reasons blockchain transactions are accessible by everyone. As for the personal information, you are buying your coins from someone, right? To get them you have to pay with fiat, either for the coin or for the hardware to mine, or for a mining contract if someone mines it for you. Bottom line if you're buying it with fiat you're leaving a trace.
