Someone in a permanent vegetative state does not meet #1, yet we consider them a person.
Yes. Yet they are not a person by any reasonable definition. They were previously a person, and I think this is why we consider them to still be one.
Also, if the vegetative state is deemed to be permanent, they are not a potential person either.
As far as I'm aware, there is no situation or state which is like being a fetus. It's unique. We can analogise, but in the end there's nothing to closely compare it to.
