There are things that are written in cursive that you need to be able to read in order to be a functioning citizen of a working republic.
It doesn't matter whether you write cursive or not. I don't; I'm left-handed. But I can look at the Declaration of Independence and not need someone to translate it for me because it might as well be written in hieroglyphics.
If you can't read cursive, someone could hand you page 12 of the owner's manual of a '94 Toyota Camry and tell you that it's Article Three of the Constitution, and if you can't read the original to compare, you'd just need to take their word for it that the Supreme Court has a 3 year/36,000 mile powertrain warranty.
To someone who can't read cursive, the Constitution is essentially like the Latin Bible was to medieval peasants pre-Wycliffe; it says what someone else tells you it says.
