I don't know why this coma thing popped up, but it really doesn't belong in this topic. It's different assigning a player to a young child character, who hasn't previously had the skills and abilities to affect the world around him/herself, nor enough capacity to hold his/her experiences in long term memory, even if his/her senses were developped enough to catch visual stimulation, sounds and touch. There are no specific memories, only vague sensations... maybe a baby well cared of and cuddled would have a different "stamp" on it than one that has been starved, left out on the open, beaten etc.
While giving some newbie a free ride of placing them in the body of a character who's previous player quit really doesn't make any sense. Everybody starts from the same situation, with no equipment or knowledge of your surroundings and history.
Life is what you make of it. If you play nice, make friends with older characters that seem to have the most things or influence, intelligence or social charisma... or just step in when you notice an oppoturnity, then you can get far in a really short time. While if you take a big risk of stealing and running, you'll most likely be a corpse, or in a rare case, get somewhere in a vehicle and make a new life, even though everyone is likely to suspect a youngster with equipment.
Edit, and newspawns obviously do have some power - they have the ability to start projects, travel freely, pick up things, plus they have the element of surprise on their side. No one sees them before they make their first move, unless someone happens to be online and check the character list. Now that's power. And seeing how common spawn-and-run thieves are, if the freedom gets abused then it must be taken away. It's totally that a newspawn has no social contact to it's surroundings and values material things over human contact. That's an action game hog-the-best-toys-and-win perspective, not roleplaying perspective. Edit2: I mean, if people were totally in character, a newspawn wouldn't even know what iron is before they see someone using it.

Though that was before the you're not allowed to know anything rule was cancelled.
