Jameson Lopp indicated that quantum-enabled recovery of theft or lost Bitcoin could severely damage trust in the cryptocurrency and negatively affect its market value

Quotes that support claims

He believes that quantum recovery will not work due to the violation of property rights and the erosion of trust. Moreover, large-scale theft would crash the Bitcoin price.

"Of course they have to be confiscated. If and when (and that's a big if) the existence of a cryptography-breaking QC becomes a credible threat, the Bitcoin ecosystem has no other option than softforking out the ability to spend from signature schemes (including ECDSA and BIP340) that are vulnerable to QCs. The alternative is that millions of BTC become vulnerable to theft; I cannot see how the currency can maintain any value at all in such a setting. And this affects everyone; even those which diligently moved their coins to PQC-protected schemes."
