As a MedChem I totally agree with you in two parts. First, deal with the root cause always better so many people pop paracetamol for EVERY headache when a lot of them would be solved by wearing glasses or even just drinking a glass of water. And second reason why I agree with you is that as a chemist, I know that is better to let our bodies do their job and ANY substance going in is not 100% harmless. So, better to avoid it if you can! Also, my mom also always annoys me telling me to stop complaining about X or Y pain and just take something and I always refuse haha so, totally get what you meant there :)
