Sure! I can also be an adult, have fire detectors and insure my property against fires instead of hoping for the goodwill of the community or the government.
It's not goodwill though, I'm paying for public services like the fire department through my taxes. I like them to be owned by the government instead of a private rentier because I don't want to pay the capitalist rent for borrowing their money; if we pool our resources we can cut out the middle-man and just fund it ourselves. Very typical human living arrangement I believe.
