"The current is the same in the entire circuit."
That is true in normal operation, but if a short develops in the wire, the current will be very high between the battery and the short. The fuse will only protect the circuit if it is located between the short and the battery. Shorts can happen anywhere that the wire rubs against something, especially the metal frame.
And the fuse will protect it no matter where it is in the circuit. Car fuse panels are nowhere near the battery, RV fuse blocks are often at the other end of the trailer from the battery on the tongue.
Ohms law means that no matter where the short is the current is the same throughout the entire circuit whether the short is at or near the battery the entire conductor (circuit) will see the same rise in current.
