I haven’t seen this in print so I’ll take credit for it until I hear a compelling claim for prior art elsewhere. Then I may withdraw that claim. 
this computer, once worth $30k, is probably worth letting someone else store!
The Internet is your new distributed storage architecture. Not just for information, but for physical items.
Think about that for a moment.
If there’s something your house that
* Is worth less than $10
* OR weighs more than 10 pounds
* OR occupies more than 10 cubic feet …
* AND you are basically storing for no compelling reason…
Why not get rid of it now, and then buy it again from Ebay/Amazon/GoogleBase/Craigslist if you ever need it again? Let some other clutterbug store it for you in their house and then ship it to you if you even need it again.
You are basically storing it in their house, playing the highly probable odds that you’ll never need it again. If you never need it again, which is the case for the vast majority of items, then the cost of storing the item has been zero dollars.. If you do, you can reacquire it cheaply in the future. Reminds me a bit of this joke
If you live anywhere with even moderate real-estate values (like, let’s say just about any civilized country), what’s that space in your house worth to you? What is that shelf space worth to you on a per $/per year? Are you thinking about moving or purchasing more shelves/storage just to get more space?
Have you heard of the virtuous cycle? I believe that if I can convince you to practice this, it may have the effect of reducing the value of that not-needed item further, making it even cheaper for me to acquire that item again, should I ever need it.
Save that trip to IKEA for shelving!
Then again, I’m not an economist, so YMMV.
