Personal Wifi anthena bad idea?

Ok let’s say you’ve purchased laptop with cash and installed qubes/whonix/tails any anonymity software you like BUT you’ve purchased a wifi anthena with your credit card on your name, (and it has hard coded mac). IF a government entity installs malware on your laptop someway how due to your neglegence, will the anthena deanonymize you completely? I know that whonix hides/changes your mac but to what extend?

The Whonix project can’t advice on how to beat governments.

Advanced non-government evil adversaries at best.
