2-3 drinks on a Friday night when you're supposed to drive home is different. I'd also say "I can drink because the law is wrong" is also not exactly a neutral take.
- I believe the law is overly proscriptive / strict / wrong.
- I believe I won't get caught
It's no different to someone speeding because "It's clear conditions and I consider myself to be perfectly safe at this speed". Or skipping a stop sign "I can clearly see nothing is coming".
