If you are a cracker, you try to take down the other system someway.
Duplicate MAC-adresses (the hardware adress of your device) or duplicate
IP adresses are very hard to determine - ar least in my expirience.
A big segment with PCs and a lot of curios and "skilled" users can be hell.

And shooting them or cutting off fingers is considered as unprofessionel.

If someone is root on his system, how do you stop him from reading pakets?
There is no way to tell a packet to avoid being read by tcpdump - or am I
confused?

You can scan and search cards in promicuos mode, but this leads back to
shooting and cutting fingers.
Or you can buy cards which dont provide this feature - this exists for token
ring.

Happy new year / prosperos ano nuevo
