There are some cases where this could create complications...
1. When the assailant/passer by tries to loot a dead body, the dead body is not dead anymore.
The victim has most probably respawned, and is at another part of the town.
It just sounds weird, to lose cash because someone picked a wallet from a corpse that was supposed to be you, while you are drinking a beer at another part of the town.

2. This could cause a script complication, if a person dies twice or more times...and someone tries to loot from the "not-latest" corpse.
3. This can be abused.
Step 1: Die with 1 mil cash.
Step 2: Respawn and give all cash to friend/deposit all cash.
Step 3: Ask friend to /c loot
The friend will get rich, but you wont lose any cash...since you dont have any.
Though the complications and abuse can be solved till some extent by scripts, through few checks on the victim's current cash.
But the current cash might not be equal to the cash he was carrying at the time of death
