Not the best example :). Death seems inherent on the timescales of the lifetime of the universe, but on our timescales, it's merely a default. There's nothing in physics or biology saying we
can't solve that; it's just an extremely difficult challenge that we didn't solve
yet. I mention it because if we classify it as default, not inherent, it means we can and
should be doing something about it.
But keeping appropriate timescales in mind, I agree with the conclusion - for given constraints, there are things that are inherent and not worth attacking, and then defaults that are merely attractors for the system state.
