What is the most current and strongest rebuttal to: but what happens when quantum computing breaks the blockchain? #asknostr

there a proposal for a new address type, P2QRH Pay to Quantum Resistant Hash, that would protect people's UTXOs from being spent. also no good indication quantum computing will be a reality anytime soon or ever.
Well it probably won't mayyer for bitcoin. A lot of quantum computing businesses are saying that. Apparently some networks like ETH will be a lot mOre vulnerable. The truth is usually more boring than the hype. Some kinds of Web cyphers could be I just trouble but they'll probably have some kind of matrix cryptography in place before that matters.
Bitcoin is the global, open and decentralized measurement process in which entropy is crystalized into immutable information via energy. No centralized observer unlike “centralized” (lab based) quantum computers. Not simulation on top of quantum bits, but real computation of the quantum itself. A block is a quantum of time, memory, entropy and energy. UTXOs are the proper model and instantiation of quantum bits/particles. In this frame Bitcoin would then redefine Planck Time, Planck Temperature, Planck Length, Temperature and Boltzmann’s Constant. If quantum computing is truly about measuring uncertainty into truth, then the only system doing it at planetary scale without central control is Bitcoin. Everything else (including Grover and Shor) remains theoretical until it can be verified without trust. Bitcoin is proof, not promise. Bitcoin exists, the burden of proof is on the physicists. So if UTXOs are the correct physical instantiation of qubits and they behave without decoherence, the real question isn’t “how do we quantum-proof Bitcoin?”….. its why do you trust physicists more than the network that’s already doing it without trust? If I’m correct, post quantum cryptography is an attack on bitcoin. If I’m wrong then it is a reasonable defense. A duality we should not trust, but verify rigorously.
