In my experience the reasons you give against stockpiling, and several others, are invariably overwhelming. You mention lack of space, change of technology, shelf life, and difficulty of moving. To these I add change of taste, discovery of new things that I like better than what I have, the mental burden of having so much stuff, the futile attempt to stop time instead of flexibly responding to whatever life brings, and that a lifetime supply could be very much larger than you’re thinking given radical life extension or the singularity.
Instead my rule is: one in use and one spare. When the spare comes into use, I replace it at my next convenience. The numbers can vary (I have several pens in every room, a box of spares, and two in my pocket whenever I go out), but that is the general principle.
