Wallet addresses traceable, not the user. There are no any means in bitcoin-like crypto to connect person and wallet or address. Also, you could have any number of addresses and any number of wallets.

So, traceability of bitcoin user depends only on this user concern. If you use it thinkfully, you can't be traced. If you personnaly provide your address along with your name, leave home address for shipping or appear personally to get your purchase, it is your fault, not bitcoin's.

To minimize such ways for deanonimization, bitcoin provide a possibility to create as many addresses as you wish. In the early days of bitcoin it was recommended to generate new address for every payment, send some sum (not equal to the sum of purchase) from your main address and pay from that address. Later you could spend a residue from that address adding it to the transaction from another new address. However, now it could be problematic, due to the long transaction time and relatively high transaction fee.
