No seriously, why would anyone need to hide their IP address from their financial transactions?
To prevent the giant NSA database from knowing every last piece of information to connect every last dot.

Every machine on the inter web has a unique identifier.
Just as you would address a letter to send in the mail, computers use the unique identifier to send data to specific computers on the inter web.
So if I send transactions out and people can see my IP, they know who I am, and can track my spending?
Yes.
