If you had to have a unique address for every atom in the solar system (I avoided the Universe), what technique would you use? Still hash and casino dice for each one?

I'm pretty serious with this question given contemplation of designing a future-inclusive Operating System.

If you really need so many cryptographic keys and won’t trust hardware then you have to build it yourself from commonly available parts and connect it to an offline raspberry pi to take out the automatically generated keys.

An example on hand built entropy generator: https://github.com/nategri/chernobyl_dice

You can do something like this for I guess 1000 dollars but it won’t be useable for real-time systems.
