It doesn't work that way. They would have to know your original master password in order to decrypt your database and re-encode it with the new temporary password. Since they do not know your master password, this idea fails.

It's more like they will push the price of gas up just to convince people that rail will save us.

I don't think an unsecured wifi is an open invitation to use someone's network. It would be similar to walking around with a lan cable plugging it in to someone's data ports trying to see if you get a connection. Also I see a lot of arguments that your computer is asking for a connection to open networks one after another until it finds one that grants it permission and hands out an IP. Wouldn't it also be your fault for connecting to their network because you set your computer to auto connect to any network it can find. Therefore you would also be at fault because you configured your computer to connect just as they configured their router to be unsecured.
