What's the point in using a balun if the feed line and antenna are
both unbalanced? Sort of a contradiction, isn't it?

The purpose of a balun is to balance the feedline, that is, cause the
currents in the two conductors to be equal and opposite so it doesn't
radiate or receive signals. Either twinlead or coax can be either
unbalanced or balanced. If the feedline is unbalanced, as you say, a
balun will prevent the line from radiating or receiving signals.
