I'm co-author of a paper which examined sneakernet in the context of interstellar communication.

Turns out to be very competitive indeed under a range of conditions. The bandwidth can be very large and the latency within an order of magnitude or two of that of electromagnetic signalling.

A 2TB M2 external SSD is ~10.7x3.2x1.05 cm^3 (without cabling, racking etc), so 2 TB / 3.6e-6m^3 = 556,300. TB/m^3. That's a problem, 86 times more volume per TB than available. MicroSD at 1TB, 16x12x1mm^3 is ~5.3E6 TB/m^3. Still too bulky, by about a factor of 9.2. That's for cold disconnected offline storage. If you want it online, with cabling, cooling, systems it's interfaced to, it would require considerably higher storage density devices. Cost is another matter. At ~$20/TB, it's$400,000,000,000 for the drives, assuming that the volume of purchase does not raise prices. Compare to the assets of these individuals. Allowing for growth, you're going to need ~70TB/second, and increasing at Moore's Law rates, 560,000 times gigabit fiber speed. So, I conclude an offline snapshot could be fit in a neighborhood or large warehouse, offline, but budget is a problem, as is updating.
If you're allowed to compress that info, that number becomes a lot more manageable. You could fit that data into most houses if you had the budget for all of the required hardware:

Hah.

Well since we are looking for hidden meanings, then clearly it must be a question designed to see who is willing to claim ownership of parts of the planet. As in: can you really say it is your home?

And since I know that I own the entire planet, then it is obvious that I can fit the entire Internet inside it.

I'm still organising your first rent bills. I hope you have all been keeping something aside to pay up. It's gonna be a biggy. And eviction from the planet would not be pleasant, so you wouldn't want to forget to pay.

Have you seen the Earth lately? There are still plenty of places to store things like that.
