Immortality + no other technology improvement is not a realistic assumption, that's why you get to a non-realistic result of "people have to die eventually" from it.

The immortality is not a thing you take and then have to kill others to not allow them to take it from you.

The only way to not die is to have a huge society that invents new treatments, discovers new physics, builds machines to prevent death from random comets, from earth's magnetic field running out, or sun exploding. The mere 7 billion we have now is not enough for any of this.
