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).
Just like you don't need to know Japanese to count the exact amount of yen bills.
Society is not supposed to be engineered for young single healthy 20 year old males.
Braille on money also doesn't help dyslexic quadrplegics with dysesthesia... Checkmate.
If you have a good, working solution that's widely used worldwide, and someone suggests a worse solution that works for fewer people, it's more than fair to point out that "your solution is worse, less common, and works for fewer people".
Your last sentence is a low effort strawman, I'm not sure why you felt it necessary to include.
