We all hoard something if you compare the amount of usage that we had. For example, do you buy movie but how many times do you watch? Do you buy a car but how many hours a day does it sit idle? Human nature is greedy and competitive, and that’s why you see kids in kindergarten fighting for the toys all the time. It goes back to the fundamental economy theory which is based on scarce resource which will never be solved. (We don’t hoard resources that are not scarce, for example, no one is hoarding air at home).
The trick is to contain your greed to a degree that you don’t constantly piss off other people. Otherwise, they will treat you like you have a disease and force you to go through the useless therapy.
