Here’s the problem. In a world of finite resources, you will end up putting a price on human life, even if you claim you’'re not.
For example, car accidents happen. Sometimes they kill people. We could prevent every single one of those fatal car accidents if we chose to devote sufficient resources to it.
Admittedly, the resource cost of doing so might be very high - for example, making the only available cars super-safe armored vehicles that cost a million dollars apiece and travel very, very slowly.
But we choose not to spend our resources on doing that, and so we implicitly put a price on human life. Whatever a human life is worth, we don’t think it’s worth paying a million dollars for car and getting to our destinations much, much slower.
If not being willing to pay the resource cost to save every savable human life is ethically indefensible, every human being on the planet that uses more resources than the bare minimum needed to sustain life is ethically indefensible.
(And even in a world of limitless physical resources, like Star Trek’s Federation, there is always one scarce resource - a person’s time. Until we achieve immorality, and repeal the laws of thermodynamics, every person has to deal with managing a finite resource.)
