We don't "have to" tell each other. People vote on representatives and assemblies/senates legislate on policy to protect the population. This is as basic as getting an army. We are in countries, we are not in no-man's land. None of us is. Your problem is you seem to only he capable of thinking of yourself, rather than the society you are in. Being responsible is one thing, protecting population from external attacks are another. Companies do not have the population's best interests in mind. They merely wish to make money at any cost (they would drug people if they needed. Some have done that in one way or another. Gambling is one such drug, used in the psychic level.). The state needs to protect their populations from such entities just like they protect them from unemployment with subsidies or from external invasion by having an army. Life in society. It's so part of you, you even forget it's there.
If you have studied history at all, you'll know that nearly every major travesty perpetrated by man has been done in the name of government. In turn, those governments generally claim they're doing it for the safety, security, or betterment of "their people". Religious persecutions, ethnic cleansing, chemical weapons attacks against civilians, caging of humans simply for possessing marijuana, separating children from their parents and jailing them for crossing of borders, and a nearly endless list of other crap - all done "for protection", or some other bullshit.
I'd say I'm the only one here that is actually looking out for other people. The rest of you are cheerleading a government that is taking away freedom (admittedly, in a very small way, in this case). They'll take a little more freedom next year, for some other stupid reason. Then again and again after that. How much trampling of rights is too much for you?
