you should maybe go take a look at how addressing in LANs work. If you give yourself address from outside your network range, you wont receive any traffic, since your router doesnt know where you reside when the packet comes back.
Your email cannot be traced by physical address, because its stored on server somewhere completly different from where you are, when you send it it also doesnt fly straight out of your computer, but it first goes to the email server that you are using.
You should read on these topics before making conclusions, but as I said, stallamian with confirmation bias is not convicable no matter what.
