pot inoculation doesn't involve stabbing, just touching the surface of the agar. What do you mean by "they can't get enough nutrient just being on the surface of the agar plate"? Nutrients will diffuse.
Stabbing is another thing - you can, in fact, use it to ship bacteria. To prepare a bacterial stab you usually pour solid medium in a sterile microcentrifuge tube, let it solidify, then stab it deeply with a loop carrying the desired strain. The bacteria, even if aerobes, will stay alive and actually create a colony in the stabbed agar; but due to their inability to penetrate the agar, they'll only grow in the stabbed hole and much slowly than on the surface of a plate, making it possible to ship the tube.
