You don't mind living in a country with a population of billions [sic], piled on top of one another? You don't mind living a country ruled by gerontocracy and probably autocracy, because that's what you'll eventually get without death to flush them out.

Senescence is an adaptation.

"You/your loved ones should die because Elon would die too" is a terrible argument. It's not great, but it's not worth dying over. New rich bad people would take his place anyways.

"You should die because cities will get crowded" is a less terrible argument but still a bad one. We have room for at least double our population on this planet, couples choosing longevity can be required to have <=1 children until there is room for more, we will eventually colonize other planets, etc.

All this is implying that consciousness will continue to take up a meaningful amount of physical space. Not dying in the long term implies gradual replacement and transfer to a virtual medium at some point.
