A thing that does not meet the definition of alive, but with proper
external input from its environment, would meet that definition.

And I've got a bridge in Brooklyn to sell you.

Right, it can change with the environment.  What is life capable now
might not have been life capable 100 years ago (an MI on the operating
table before the advent of electricity).  You rightly clarify that it
is property of the thing and its environment.  I think this is where
the need for the 3rd category arises: dead or alive are both
environment independent notions.

Perhaps it will soon, I don't think it has yet.
