Let's ignore space, where currently the highly elevated risk is well known to the few participants. If we could undo car and plane crashes, we would do it. We cannot, and my question is whether we want to force the same property on accidents that we currently can safely undo.
Another example: Let's assume ownership of a house is defined by a blockchain. Through a mistake, ownership of your house has been transferred to someone else, or lost to an address with no existing private key. Alternatively, you were in the process of buying a house when the same happened.
Would you be happy with the outcome of this simple mistake being irreversible?
If not, and if you think litigation should retransfer ownership to you, what is the value of an immutable ledger, if the house went to a malicious party who does not intend to perform the transfer on said ledger, or to an address without private key, making transfer not possible in the first place?
