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.

I don't know why your would do it that way. There are numerous exchanges that allow for anon accounts. Just hold your bitcoin on one of those and transfer using a disposable device on public wifi like a $20 smart phone (in case the mac address is logged)

You need to somehow receive those gold coins. So shipping address from the vendor.
The vendor may not be as meticulous with protecting their identity. If the vendor can be identified then they could lead to you.
When the vendor sells their bitcoins it may also lead to their identification.
You could potentially be identified by the origin of your bitcoins too.

Yes you are right, I did not consider the peculiarities of these coins. For the Monero I heard a long time that it is used to pay on the black market.
But still, any contact with the exchange or Fiat money, you can immediately recognize.

Monero is used on the darknet. But fiat (cash) it used for more illegal transactions than anything else in the world.

If you sell your bitcoins to someone who remains careful with their identity and sell them for cash then you cannot be identified.

Your wallet and the transaction can be identified but if you are careful then your real life identity is not revealed.

Online casinos and mixers can also be used to mask the origin of bitcoins.

My proposal for a system called "walletswap" would make tracking much more difficult too.
