I hear you, except in reality there are plenty of places a new business might expect users to navigate to their website from, e.g. their URL could be listed in a common proprietary platform such as Yelp or Twitter, and it could also be in a marketing email or even a business card. Hopefully new generations will understand what a URL is, and perhaps some informative campaigns could keep the public aware. We learned how to describe directions around a cute town on a piece of paper when I was in the 2nd grade, so why shouldn't elementary schools teach basic internet essentials to kids at some fairly early grade level?
