Since I didn't say 2FA isn't effective, I'm not sure why you feel the need to be aggressively dickish by calling me irresponsible, but I hope it gave your day purpose and meaning. What I said is accurate. 2FA is not some sort of panacea that makes your private info safe because in some cases - like app permissions - it isn't even applicable. It is also vulnerable to theft since most people with 2FA download an app on their cellphones, which are then lost or stolen and give access to two factor codes for the same accounts you want to protect. Never mind the pitfalls of email or SMS authentication codes that some services rely on.
I agree with the larger point that people need to use two factor authentication as a first step because it is one of the easiest ways to protect your email, your banking info etc from thieves, but a lot of people think downloading Google Authenticator on their phones means they're impervious to hackers. That isn't true, and it isn't irresponsible to say so.
