Look up. Can you see the sky? That's because the government sets pollution limits. That's evidence you ignore.
Look at your post. You're publicly questioning the government. That is because the US Military has prevented another government from ruling you and silencing dissent. That is evidence.
Can you walk or drive down the street safely? That is because the government sets safety standards for cars, and rules for driving and punishes people who break those rules. That is evidence.
Do you have a home? That is because the government protects property rights, so no one stronger than you can simply kick you out.
Look around, basically any time peoples' carelessness or vindictiveness is not hurting you it's because the government has set laws against it.
