So that that initial pairing is more secure. Zigbee etc. tries to get around the whole thing by requiring that the pairing process is done from a 5cm or something distance. Imho that is good enough but I don't know how far you could extend it with directional antennas etc. That anyone can reclaim a device they hold in their hand is a feature.
