I don’t have any ability to make choices about it that depend on any conscious valuation. But do you doubt I value it because I am not buying or selling it? I suppose near infinite, in that I would certainly sacrifice everything I have to protect it - given it represents the survival of all of us - which for me at least would be the apex of value. It is worth noting that value can often be measured in currency, but not always. It is ultimately an ordering of everything, by kind and quantity. In the end, even money is just another “thing” which we value on a gradient and relative to context (what we need to survive, we value a lot. To live Without stress, a lot, but less. More than that, even less, even if we are ambitious.) Market value comes directly from each of our personal, “intrinsic” as another commenter called it, valuations. There is no market value where there are no personal valuations. But there can be personal valuations where there is no market. Each of us still prioritizes what we have against what we want, and the costs to us of that, even if we were hermits. Each of spends our time, the ultimate resource, based on our relative values of things. That is the source of all “value” or “worth”. Individual or (and before) collective.
