Let's say it's not just booting from it, but constantly reading.

Let's say no one implemented the checksum. Edit: I forgot that floppies have a crc check, my bad.

Let's say the machine that can write the new disk is physically far away from the machines that read them. (Or the guy with a stack of new disks -- which are harder to find every year -- his office is some distance from the control machine).

I guess I assumed it was only reading from the floppy, not also writing to it.. that doesn't seem like it would last very long at all without encountering errors (at least based on my memories of reusing floppies until they were completely worn out)
