It's wild to see you downvoted. Only about 10% of blind people know braille. There are many more people who have visual impairments but are not blind. Braille is not a universal solution (though I would rather have it than not have it).
Chiming in to complain that a good, working solution to a problem just doesn't happen to solve ALL PROBLEMS is just banality or perhaps pedantry. Unless it was also proposing an alternative that might do better...
Braille on money also doesn't help dyslexic quadrplegics with dysesthesia... Checkmate.
But you don't need to know braille to learn how the most common bills are marked.
Just like you don't need to know Japanese to count the exact amount of yen bills.
