QC is not something I've researched much, so I don't know how much is science vs scientism.
If reality ontologically blocks scalable QC, then the "full-spectrum quantum" is a narrative weapon more than a physical one.
BTC's real risk reverts to:
- Capture of rails (app stores, nodes, KYC).
- Paperization & containment corridors,
- Legal/regulatory assaults on self-custody,
- not superposition-based math magic.
If time is discrete and ontology weird:
- QC still works as long as there is a stable effective Hilbert space.
- But unknown deeper limits could prevent Shor-scale factoring.
- No one can prove ahead of time which world we're in.
A Bitcoin block is proof that given current hardware, energy prices, and incentives, this ledger history is the locally cheapest one to coordinate around and the most expensive one to challenge.
