A lot of parents (and employers) come up with consequences that are not really logically tied to behavior. Often, they just try to "punish", which fails with a lot of kids, or even backfires. My oldest son has (among other things) a high tolerance for physical pain (and, as an adult, a red beard, when red hair is a trait known to be tied to high pain threshold). He could be quite difficult as a child, both because he didn't much care when his risky behaviors hurt and spanking was pretty pointless. But when designed right, consequences did work. Punishment did not.
