Because not all packets have position information?  E.g., messages or 
the (abominable) weather station without a position.

The concern is bandwidth utilization, and hopcount is a major factor in 
the bandwidth picture.

We could limit hops based on physical distance, but that's a bad idea 
because of things like band openings, balloons, satellite operations, 
etc.
