Without using any of the tools to obscure internet activity, how are you going to track me in the following situation.
Set up a node using public WiFi, and a copy of the blockchain I've already downloaded.
Receive Bitcoin into that wallet.
Use the Bitcoin to purchase gold coins.
Wipe the hard drive on the computer with the core node.

Let's start with the lowest hanging fruit. Where did you acquire the BTC and gold from? I assume the coins didn't magically appear in your wallet. If you bought the coins from an exchange or ATM, you probably had to give up your identity, or at least some identifying details -- phone number, etc. which can be used to track you down. Even in a pseudonymous P2P cash transaction, you are still usually connecting through a centralized service (e.g. Localbitcoins) who knows certain things about you. And meeting in a public place to exchange cash for coins could potentially expose your identity as well. On the other side, you need to transact with the gold dealer. Many gold dealers require ID even below the $10,000 reporting threshold.
There are other more paranoid considerations. You didn't obfuscate IP address. Where are you -- an internet cafe? The transaction is linked to that specific time in that specific internet cafe. Are there cameras? How many potential witnesses?
