You get a replacement if lost or broken. Then re-authenticate and restore from a backup. That's how it's done with iPhones.
And about the police, you destroy or lock your device. If that's not %100 secure, it's OK because that's part of the risks about going against the authority. Can you imagine revolutionaries not revolting because the police might hit back? The risk of being caught by the police is part of the outlaw experience and you will need to actively try to avoid it.
Who's providing the back up? How do you re-authenticate if you lost the thing you use to authenticate with?
It's easy saying it but I don't understand how you do those things. If the answer is you need a password to access the backup and to access an account to re-authenticate, I'm not enjoying the irony. If the answer is to trust a company like Apple, Google, Microsoft with the literal keys to my kingdom then this thing misses the point.
Currently I'm in control of my authentication, why would I hand that to some company and hope I don't annoy them enough to ban me, or just randomly cone up against their AI guardians.
On iPhone's case it's Apple and it is accessed by a password but in this hypothetical scenario it could be your own infrastructure or another device you own and that one can be password-less of that's your thing. Having one password to activate your authentication device is not a gin deal, it can be something like
mnemonic seed etc.
The hazard is not one password but endless ways to authenticate through endless passwords.

I was more talking about border control, which has been known especially in the US to believe that non-US citizens have no rights at all and even the rights of US citizens and permanent residents have limited rights.
And for what it's worth you can end up having your devices seized or being executed by police simply for the "crime" of being at the wrong place at the wrong time because the cops managed to fuck up the warrant or its execution by blowing up the door at the wrong address.
Police going rogue are a threat model everyone should be aware of these days.
I guess the US has its problems. If that's an issue, don't go there and if you choose to go, don't bring a device with you that you can't tolerate being investigated by the authorities.
It's unreasonable to say that all your problems in life must be solved by this one tech or it's not worth having it.
