I agree, one cannot make things perfectly safe. We pilots all know that, more than anyone. Flying is a hazardous activity. Don't need to make it more hazardous than it already is. But the good pilots work at making it safer each flight. The good pilots do preflights. The good pilots visually check the fuel level. The good pilots perform a run-up. The good pilots practice emergency procedures. The good pilots communicate with the other pilots in the pattern. Good pilots know that making accurate position reports in the pattern, that we all share, is not an unreasonable expectation. The bad pilots say "I don't have to". I will call out every SOB that says that.
I get making mistakes, we all have. But NORDO is a deliberate act.
@SixPapaCharlie is absolutely correct. There is no defensible argument for not using all available means.
