Why do you call that behavior irrational? Seems like it would save some bandwidth costs, as the parent suggests.

AFAIK nodes get paid for serving data and they can set the price to be higher than their bandwidth costs, so refusing to serve data is refusing to make money.

If you are the only surviving node with the data, then it's called extortion or holding the data hostage.

Preventing that kind of problem is basically the point of Filecoin and similar systems.
