Maybe Satoshi already "burned" his UTXOs by moving them to an address where he doesn't know the private key.

I wonder about the advancement of Quantum computing over time and the potential ability to break the current double elliptical cryptography. I believe Bitcoin the network will be able to defend itself by introducing Quantum-proof address types over time, and individuals can move their coins from legacy address types which may be vulnerable hypothetically.

It will be interesting seeing what happens to lost bitcoin and satoshis coins in this thought experiment.
