100% agree this is solvable with words and conventional form fields. But also - it’s usually bad idea to disable a form submit button. It deprives the system an opportunity to tell the user what they need to do (i.e. if it’s disabled you can’t show an error message) and for the same reason it’s bad for accessibility.
