That physical cash can become damaged is nothing new. Maybe this implementation could be easily damaged in some way, I don't think this threatens the concept of silicon cash generally.

Physical cash is both very resilient and if damaged can be replaced. This is neither.

The notes are more durable than linen currency and less durable than polymer currency. We found this to be an acceptable tradeoff. Most of the note can be destroyed but the funds still claimable. There is an envelope of durability properties associated with physical cash - Kong fits within most of these. Of course there is opportunity for improvement which we hope to address in future versions.

I'm not sure what you're making that assertion on the basis of. The note has redundant electrical connectors. You could melt the bulk of the note down and still claim the Etherium from the secure element. Hypothetically you could have redundant SEs.
