I think this is just generally a way to justify doing whatever it is you want, and implicitly deflect anyone telling you you are wrong by adding a criticism of those who don't do it.

Sometimes its good justification: if you have never failed you don't take enough risks. Fair enough.

But i'm sure an alcoholic would say something like: if you've never been fired for being too wasted to work, you don't know how to have fun (maybe they would be a bit more subtle, but you get the point).

I think its better to just be honest with yourself, drop the implied moral criticism. Instead of saying "if you never miss a plane you spend too much time in an airport", just say, "For me personally, i find it acceptable to miss a plane every now and then if it means i don't have to go to the airport 2 hours in advance" You're making explicit the trade off, and you're not going on some high horse that there is something wrong with people who make a different trade off or have different priorities.
