So I'm just full of hope that with every setback we'll be wiser and better and be stronger :-)

I sure hope so, and I agree very much that "freeze" is a lot better than a long-lasting chain fork with the risk of double spends, etc.

Still, I think it's very important that historic data from the blockchain is always available, and it should not be that difficult to achieve, even in a frozen blockchain. After all, long-term immutable robust storage is one of the selling points of the blockchain technology, then it looks pretty bad that a small bug causes a total outage.
