Also note that script is historically mostly used for communication over large distances and times.
Historical scriptures (such as the bible) got transported across half the globe and copied and passed down for more than a thousand years. The scripture transcends both space and time.
If you only want to communicate with your neighbour, you don’t need a lingua franca. Lingua franca is exclusively for writing down, and communicating over very large distances (such as the internet). In that case, no pronounciation is needed. So it is possible to have an abstract sign language that doesn’t even have a standardized pronounciation.
This might sound absurd at first, if you never thought about it, until you realize that is how a lot of our information is already transported. There are a lot of sketches and visualizations of important data that are graphics, plots, charts, drawings, and such, that don’t have a standardized pronounciation. The information is transported visually.
