Another cost is what i call “maintenance cost”. The thinking about, cleaning, repairing, recharging, moving, etc. Even a pencil. I must store it, remember where it is, take it out, clean under it, sharpen it, move it out of the way to get another thing, and finally discard it. These costs compound with each new acquisition.
