Charlie can be a billionaire and own his own private street, but neither alice or bob can walk into charlie private street, they need to deliver their tapes to charlie and charlie will have to physically transport those packages to the other end of the street to be delivered from alice to bob.. and that is what charlie is refusing to do because he find alice an asshole..

Now alice and bob are not being prevented from meeting in person somewhere else.. hell alice can even build her own street all the way to bob house if she can afford it..
