Freeze from theft but can recover if they use a zkp
No matter what it's a really bad idea to mess with someone else's property. Who gives core the right to freeze others coins? What are they going to do next, reverse the chain?
The point is, anything happens on Bitcoin should be opt-in otherwise it's a violation of property rights.
Quantum is not even a real threat compared to this and it's negative effects on Bitcoin.
If you think your coins are at risk of quantum you should move your coins not someone else's
Then what do you suggest they do?
Nothing, let the owner move his coins if they feel like there is a threat. Quantum is not even close to be a real threat to Bitcoin.
Practically impossible to guess those private keys.
Next they will come for everyone else's coin with a much faker threat.
And if quantum comes and steals their coins it’s all good?
If such a threat were to exist (it doesn't), that would be the incentive to move coins... not fear of lockout.
No one is forced to accept stolen coins, Lopp's argument is disingenuous. If you receive abandoned coins you suspect were stolen by QC you can burn them.
economic disruption
This is the not-so-quiet part of the proposal, fear of dilution by reintroducing abandoned coins onto the market. Lopp undermines his own argument, they're not afraid people will be forced to accept coins, but that they will happily accept them.
This is not a technical BIP, it's a vanity one trying to impose a view on the market. The very market fear driving it is also what undermines it, you can't fight the market. Someone stealing a satoshi amount of coins will also buy the hashpower to confirm the tx.
secure the value of the UTXO set
A functional QC would effectively be a winner-take-all coins, candidates in the running to have it already have access to a material number of coins (Google, Microsoft have countless passwords emails 2FA to custodial platforms and password managers).
A QC could also sign for any software distribution, enabling untold backdoors into systems. There's no change to Bitcoin that can protect Bitcoin from a (fake) QC threat because Bitcoin is not the only link in the chain.

Every scenario is expected.
yea. this is not a freeze but essentially a multi step unlocking
Sounds a lot like Ethereum to me
Many such cases
And people say Bitcoin has ossified.
