So in essence you think there should be NO LAWS what so ever? Just let people do anythning they want....anywhere they want... anytime they want... any way they want...???
Do you honestly think laws/rules/restrictions have no purpose what so ever and serve no good?
Believe it or not, some people will "consider" doing something and when they realize it "might" have legal implications (driving intoxicated, robbing a bank, flying a drone over a wildfire) they decide to NOT do it.
Of course no law is going to stop EVERY bad actor but laws/restrictions do work and statistics have shown they do so across the board.
