Unfortunately, there's no widely supported way of encrypting the traffic of individual users on a publicly accessible network. WiFi is designed to trust everyone on the LAN/subnet. But LANs are not secure. People roam between networks all the time. I have around 20 WiFi networks saved on my smartphone right now. Sadly, people are trained to password protect their WiFi these days. Other than security issues, bandwidth caps and the risk of being held accountable for your internet connections are of concern to a lot of people.
