Agreed, it's not optimal. I've been thinking about this alot lately actually, I think there's always going to be friction of this sort. You could argue it exists at all levels, for example when fighting infections your body often damages/kills it's own cells. Ofc. you can die from an overactive/badly tuned immune system, but more often, people die from not having a strong enough one! But we're not cells, are we.
