I think on the one hand, you're paying in taxes or HOA fees or tolls for roads. They're not free. Now, is it more in your face with tolls? Yes. Is it more expensive? I really have no way to figure that out.
On the other hand, I strongly believe that you should have disclosed to you something that is unusual or not what a reasonable person standard would assume in a given transaction. So while you would be fine (IMO) if you didn't "disclose" electricity is charged, or water is charged or that there will be taxes say - that's fine - no one is caught off guard by that and smart buyers would know to also look at general COL in terms of the electricity rates etc... But there cannot be many homes that only have a toll road to them. And as pointed out - who would think to ask "Is there going to be a non toll road to my house?" - that's almost like asking "Is there going to be a way to access this house with a car?"
