I don’t disagree that things are lost. But on the other hand, there are things that the new timeline has that the old timeline didn’t as well. In the new timeline, the younger brother also has experiences that his counterpart in the old timeline did not.
By choosing not to destroy the timeline to create a new one, you deny the new-timeline younger brother his experiences, as well as everyone else in the new universe. Either way, something is lost. It seems that the only reason to treat the original universe as special is status-quo bias.
