Why can't we teach this in schools? My high school curriculum covered the basics of the UI elements - window, menu bar, URL and such - in addition to OpenOffice and the basics about internet (this was 1998)
I couldn't resist adapting your argument for food:
Why exactly should food be accessible for all people at all? When you are too lazy or dumb to grow your own food like it was before the coming of Jesus, you will think that McD's is the agriculture industry. That's the problem with today's agriculture. It's too accessible for too many ignorant people.
And URLs, canonically, don't require DNS to function.
