Well, if the law considers the ceasing of life in a human body to mean that that person no longer exists,
then life is clearly the key ingredient to legal personhood.
If you have a physical or mental disability or functional inability -- no matter how severe -- you're still a person, with all the rights thereof, as far as the law is concerned.
So, a disabled person who is in a completely-vegetative state still has full legal status as a human being,
while an otherwise fully able-bodied adult who has just died is not a legal person anymore.
What changed? Only the presence of life.
I'm not sure that we agree on what life is, or what a vegetative state is. If a person is brain dead (all higher brain function gone) but the brainstem is intact, that person can survive years and years. They will never have another thought. To me, the person at that point is dead, although the organs are alive.
Depending on what type of vegetative state a person is in, they may not have full legal status as a person. At a minimum, a parent, spouse, or other party can be appointed to take over making medical decisions (which can include the removal of artificial life support).
Even after a person is declared dead, the cells, tissues and organs may be alive for some time. If they are taken out of the body, is that person still alive? Should an organ transplant recipient inherit the property of the person who lives on inside them?
