You missed my point, the government doesn't need track the blockchain itself, they just have to track the transactions being made with it. Far easier and very doable task.
No it's not. It's encrypted and decentralized. To be able to track transactions to an individual in a country at their house means breaking encryption and the block chain. Otherwise it's just random packets on the internet. You have to be able to man-in-the-middle every packet coming into a country and then decrypt every packet to see if it is blockchain, then decrypt the blockchain to trace to an individual.
ANY tracking and Idenifying of the blockchain means you have the ability to decrypt it in transit, which means you just broke crypto, blockchain and digital banking.
You might think it's easy, but it isn't at all. If you have a very secure house, but give the keys to a friend and say don't go in my bedroom, that's fine but they CAN still go in the bedroom if they want. Same thing. Once you can track/trace/identify blockchain you have the keys to house and I guarantee you will not stay out of the bedroom/blockchain.
