In a coordinate system position is just a label for the points, so we can distinguish between different points. Then why we use a position vector to specify the position as it is just a label and nothing else. We can use colours if we want to label the points and it would be fine. For example, Paris is a label for a specific location on earth and it does not have magnitude or direction. Please explain it in as simple terms as you can do not use jargon.

How far is Paris from Los Angeles? With a coordinate system, you can determine the difference between these two points by knowing what their coordinates are. You would not be able to do that by calling Paris blue and Los Angeles red.
If you sailor or pilot planning a trip from one place to another, you need to know the distance so you can fuel to the right among and calculate your ETAs. Also, knowing the coordinates tells what direction to head.
