Sure, but that doesn't solve the problem of shortage of ethernet cables

If the shortage is not of cables in general, but of cables that are long enough to reach the current connection point, then a switch would help.

Maybe they have plenty of short cables, but not enough long cables to get to each person from the main network switch.

Adding a switch closer to you means multiple people can share the one long cable.
