You&#x27;re being facetious but I will address a few of your points regardless.<p>&gt;Going for a walk? (Are there sidewalks anymore?) Have you negotiated with each individual sidewalk owner for right of passage?<p>If you like walking around your neighborhood, then you&#x27;d probably live in a neighborhood where you&#x27;d either have ownership rights or an easement to walk around a bit.<p>If you like walking around at work, you&#x27;ll probably want to work somewhere that has those opportunities available.<p>Around businesses? Obviously every business can make their own rules about their property but I would guess most businesses would welcome people, potential customers, walking in front of their store.<p>As for roads I will let the reader research that out; there&#x27;s been plenty written on private roads. Private roads predate our current public road system so I&#x27;m not sure what&#x27;s so unfathomable about them.<p>&gt;Lucky thing you saved some extra breathable air coupons<p>Air is probably too abundant for people to want to try to commercialize. It would be a failing business.<p>&gt;I was struck when I read that last line at how dismal a world it would be to live in<p>It&#x27;s unfortunate that you lack the imagination. In the past several centuries we have seen a level of personal freedom which is unprecedented. With that increased freedom we have the highest standard of living, ever. Now when someone comes along and theorizes on how we might increase that freedom you seem to fear the possibility of change--like the slave afraid of what&#x27;s beyond his plantation.<p>Luckily, this isn&#x27;t really written for you. There will be those who will read this and wonder &quot;Could we really make private roads work?&quot;, they will do the research and come to their own conclusion. You may think this fringe, and it may be, but it does not take long for the fringe to grow.
