We shouldn't value people simply because they are scarce. People are valuable intrinsically. Identical Twins don’t have less value because there are two of them

We shouldn't value people simply because they are scarce. People are valuable intrinsically. Identical Twins don’t have less value because there are two of them. A mother is not less sad when one of them dies as compared to a mother who doesn’t have twins. Trying to make such a comparison of value is gross. I do appreciate that not everyone agrees with that view, and that capitalism tries to value people at their output but intuitively plenty of people find that sort of thing wrong and ignoring that intuition is something I’d argue will not end well for us as a society.
