They don't need need money. What was stolen was some sort of "digital assets". How are they going to cover that, I have no idea, but let's not equate crypto assets with money. If someone would have stolen my bike, i wouldn't be saying "they stole $1000". They stole a bike, which could or could not be recovered, and which was or wasn't covered by insurance.
And if thieves stole a bag of paper from you, that happen to have the number $100 and some other artwork written on them by the government, what then? It's not money, it's just some "paper asset"? You're just showing your own personal bias about what the definition of money is.
Yes, and we could have a paper money system where a registry of stolen serial numbers is kept and they can’t be deposited at any bank or used to pay the government ever again.
