By design all movements of bitcoins are in the open, so I don't know about not being traced.

Because when you create a new BTC wallet you give the network your SSN and other identifying credentials yes?

Also, I can buy a pizza for a coworker in a different country without worrying about exchange rates or anything else.

FYI, everything you said can be done with cold hard cash.

You can buy your coworker a pizza with your credit card today. At most the fee would be 3%. From start to end the whole process would take no more than 5 mins. Plus, pretty much every decent pizzeria on the planet already accepts it as payment.

The BTC transfer fee is something like $20 now, more than the cost of a pizza, and the transaction might take like an hour to clear? Maybe it's fine if you don't mind overpaying, aren't too hungry, or you enjoy cold pizza.

Segwit transfer is currently at $0.003, and a transaction with enough fee processes instantly. It takes 6 confirmations for a guarantee (but that will settle over the next hour). Pizza deliveries get paid in cash through many extensions that provide BTC2CASH purchase.

I can bet you buying a pizza in Spain with Spanish currency using a US card will charge you a foreign exchange fee.

That sounds like a personal choice. There are plenty of banks that don't charge fees for purchasing in foreign currencies. Monzo and Revolut both spring to mind here in the UK, and I believe both are now available in the US.

Is there no exchange rate from your country's currency into Bitcoin?

Yes, but there are usually no exchange fees.
