The folks who vote yes are, to be blunt, lazy. Allowing the country to vote by mail would lead to massive fraud. If allowed to vote by mail-in ballot, it would then morph into using your computer to vote. Even more fraud. Mail-in voting should be reserved for those who can’t make the trip to the voting booth due to illness, disability, military service, or other things that wouldn’t allow them to be available on voting day, to be determined by the individual states.
