Two words: Gray Market.
Thank god for the underground Web. Gun sales there are going to soar. Install the Tails OS on a flash drive, run it behind Tor browser and get all the guns you ever want without leaving a trace of Internet fingerprint. They can’t tax what they can’t find, and they can’t find it if there is no trail.
Hope you’ve got a VPN running and are using DNS over HTTPS or you’re still leaving a trail, TOR or not.
