If your neighbor doesn't use the public internet for whatever reason, then making your neighbor pay for it is a waste of resources.

And some people do not have cars or children in schools or use the food banks or go to community college.

Not everything is about the individual cost/benefit, and individuals can benefit from society wide benefits.

Further in this direction. The neighbor that doesn't use this internet will still benefit from the value of new jobs and opportunity that it will bring.
