We are not expecting everyone to learn sign language either, there are many forms of non-verbal communication - even wow! Imagine this! - written English!!!! How hard is that?!
How hard is not the question, rather how practical is it? To think of the numerous times that one encounters others during the course of the day and interacts with them orally, to then transform each and every one of those interactions, even the brief ones into an exchange conducted in writing is unrealistic and impractical.
