If what you want is to have the reader make choices, and each choice takes them to a new page, you don't need variables for that. You can write a story like Eternal or Necromancer without variables.
A story like dead man walking needs a lot of variables and scripting. If you want the story to "remember" the choices the player has made, you need variables.
to your example: you can give the reader a choice if names, but without variables, you'd have to write a separate path for each name.
