Freezing other people’s bitcoins is wrong, no matter what the motivation. In my view there is only one way to preserve Bitcoin’s censorship‑resistance without violating that principle:
Introduce quantum‑resistant addresses - By adding a new address format that is provably secure against any foreseeable quantum attack, users who consider quantum computers a real threat can voluntarily move their funds to those addresses. The choice remains entirely in the hands of the coin holder. If a holder decides not to migrate —whether because they have lost the private‑key, because they distrust the new format, or for any other personal reason — then they accept the associated risk. The potential loss is a direct consequence of their own decision, not of an imposed freeze.
Should quantum computing enable the reactivation of old Bitcoin addresses, their influx may cause a crash in the price, but the price can recover. A temporary price-correction is not a reason to compromise the protocol’s core guarantees.
Preserving Bitcoin’s immutable, permission‑less nature must remain the highest priority.
