It's worth considerably less if you make any attempt to count it accurately. The market capitalization reflects the fact that old unused wallets are unused. If they stopped being unused, market capitalization would drop.
In some sense they are even completely worthless - just tokens in a wealth redistribution scheme not connected to notable real value production.
If the system does crash, nothing of value would be lost. And we would be rid of ransomware.
