>If they are in a permanent coma I see no harm
I see where you're coming from, but even "permanent" comas aren't set in stone. If they had a will that instructed the plug to be pulled if they were ever on long-term/"permanent" life-support then sure, you're in the clear.
>a fetus has no friend or anyone that would care if it died.
So only socially active people have a right to life? All my friends and family just died in a plane crash, I was the only survivor, and now I'm in a coma. Why would my right to life be forfeit in that scenario, but not forfeit if one other person just happened to survive as well?
>How about you just stop feeding them. No NAP violation there.
I'd say this makes sense for the most part, with a few caveats. If the insurance is all paid up, or there's a family member/friend that's willing to cover the bills, then obviously you shouldn't pull the plug. However, I would argue that if the coma patient's will explicitly stated that the plug not be pulled, the hospital has an obligation to keep him alive, and charge the expense to his account for him to pay when/if he wakes up.
To relate this all to abortion, I'd say it depends on whether or not you consider the act of copulation to be an implied contract to take care of whatever offspring transpires from that act. If it is an implied contract the parents have an obligation to either care for the child or transfer care of the child to those who are willing to do it. If it isn't an implied contract, then either abortion or evictionism, depending on your interpretation, is justified.
