They don’t send reusable codes, that person is talking about keeping the same phone number and receiving codes via text.I don't know about anyone else's experience with (specifically) Google's 2FA, but for me what happens is that a text gets sent to my phone that says "Please verify it was you trying to sign in to your account", and then there is the choice of tapping "No, it's not" or "Yes, it's me." They don't send me a code or number that I can just keep on hand to use over and over.
Like others here, I'm all for heightened security, but I'll go back to my main point, which is, what if I lose my phone, or it goes belly-up, or I just plain don't WANT a smartphone a year or two from now? Because as far as I can tell, the only way for me to use 2FA with Google is to own/have possession of a smartphone for the rest of my life.- If I am wrong on that, someone correct me...
2FA is generally available via text, email or app so no, you are not required to possess a smartphone for the rest of your life.
That being said app based is becoming more and more popular as it is more secure.

Figure if I am not typing my password often it would not be picked up by spyware on the computer (if there is any).
