This is the perspective of someone who has never lived in the US. There's reason mail in voting is so cherished in the US: the majority of the military votes by mail. By the way, this is equally true in Canada. But our votes are too few and diffuse to make as much of a difference.
Voting by mail has worked fine for over a century until someone decided to politicize the mail system. In the US, they can track their ballot request, and track its return and processing. And if there's a signature mismatch or other irregularity, most states will actually contact the voter to cure the ballot, before Election Day. So no, they don't need to get rid of VBM. They need to tell the politicians who are politicizing this to screw off and to stop disenfranchising serving men and women, students and the elderly.
