Survival is definitely valuable, by simply allowing you to produce value longer. I think the problem is that there is no 'long-term' factored in how we measure value.
...can you please take a step back, read this again, and think about what it is that you're saying?
This is always implicit when speaking about economics. Don’t attach too much meaning to “value” , or “purpose” , or any of those models. They’re just describing a model of reality, not prescribing it.
TLDR: “value” in economics != “value” in Buddhism.
