hoarding
goes along (to a certain degree) with excess consumption) -- but this is the drive to gather too much (to the point of unrealistic expectation of "using" any of it) around oneself
tougher to nail down, as some planning inevitably involves storing away supplies goods and all kinds of things for the future -- what I want to measure is how far beyond the realm of sensibility an individual is -- this however makes it very subjective and abstract in a way (tough to nail down with any rigor)
