Yes I do Agree with what your Saying. But if Quantum Computing is breaking Cryptography then we are in  trouble in so many sectors.  I'm sure it will break the banks first.

If bitcoin was not there in picture then this same investments would have gone into gold and silver to protect from dollar hyperinflation
Now that bitcoin is there in picture part of the same money which would otherwise be invested in gold and silver would be invested into bitcoin

This scenario might reverse if encryption breaks.
To be on the safer side 
Gold and Silver are hard assets with all the properties needed for money as described in the article

Why Silver is needed in the Portfolio

If Quantum Computing breaks Encryption I'm not sure Silver will save us. 
I would Rather Run Multisig to mitigate Quantum Computing (for a time)

Also agree on the Territory. :)
