Why should any disease be cured if not to extend the life and quality of life of the person suffering it?

If longevity becomes so prolific that overpopulation becomes a credible concern, then the right of the living will supercede the right of nonexistant future people. It makes a lot more sense to ration birthrates than it does to ask someone to die so that they may make room.

The improbability of immortality does not mean that life extension is worthless. Is striving to reach 80 asinine because we'll just want more? Should we have been satisfied at 40? The status quo is no argument for what we should want to achieve.

In fact, I'll argue that any serious life extension will have to come with a similarly extended lease on quality. Senesence will need to be stemmed upstream, so more of your 120 years will be good years.
