I hope you're right.

Regarding bitcoiners, they will definitely not attack the network, only if it is as a hack to test security, but even if a bitcoiner manages to break a key or the blockchain, he would only report it and not steal funds.

But I believe that some organizations would be interested in taking down Bitcoin, because ordinary individuals will not be able to access quantum computers, only governments and multinationals.

Perhaps some government or a company competing with Bitcoin wants to sabotage it.

That's why I think they should start working on post-quantum prophecy, it doesn't seem like they're worried about it.

Many believe that hashes already protect public keys and this would be enough to resist quantum computing. But if no one can make transactions for fear of exposing the public key, it would make all bitcoins useless. Who would want a currency they couldn't use?

Possibly the solution does not involve changing the encryption itself, but if they can find a way to protect the public keys during transactions it may be enough, until they discover a way to derive the private key through signatures, I don't even know if that would be possible.
