Just too vague to be useful empirically. Using tokens as a proxy for emotional investment may make sense to an economist but from a psychologist's perspective it is a profoundly flawed approach. At the least, any notion of “amount of wealth” is unavoidably relative to local conditions which makes the whole thing opaque and ineffective either as a source of potential insight or as a measuring rod.
There just isn't enough intellectual/theoretical support to allow an empirically testable hypothesis to be proposed.
