How likely is it that you will have enough colliding images in your photo library to even trigger a review?
I'm guessing you need at least 5 images, perhaps much more, to trigger it. In any case, 1 image is definitely not enough.

It is akin to cops wanting to search a car. They don't need a warrant. They only need to follow the car until it breaks any number of traffic laws. Then the resulting traffic stops lets them talk to the driver, who seems evasive, which gives them probable cause, which gets them a warrant to perform a full search. The accidental collision, week evidence of an offending image on the phone, opens the door to whatever other investigation they want to do.
And the police probably won't be using any neural hashes if they have access to your device, so I'm not sure what you are talking about.
Unlike Lavabit, I don't think Apple will ever close up shop to protect customer data.

Why would people pay a company to falsely accuse them of horrific crimes?
Mine doesn't. If Ubuntu or ClamAV is scanning all my photos and reporting the results to Canonical against my will then I will soon be having words with Mr. Linus.
Because if some local police agency like the FBI were altering code on an open source project as large as ubuntu then the world would know about it pretty quickly. The linux community would burn every bridge with Canonical and ubuntu would disappear overnight. The idea of the FBI adding malware to ubuntu unnoticed, malware that openly scans files and reports to remote servers, is the stuff of comic books.
This is not about child porn nor about what AV software can or cannot do.
It's about normalising mass surveillance and implementing populace control. They don't want another Snowden to scare the public with reports about "backdoors" and mass privacy violations.
They want the coming generation to perceive it as normal. Because all phones do it, hasn't it always been this way, and think of the children.
Oh, these dissidents in $distant_country that will be muted and killed using Apple's shiny surveillance tech? Well, evil governments do what they do. But we are not like that. Over here it is only about the child predators. Trust us.
Apple has been an opponent of these developments for decades. Now they are spearheading it.
Platform owners like Google, Apple, Twitter and Facebook should really keep stuff like that in mind when they deploy algorithmic solutions like this.
Like dhosek said, the manual review step should reduce the risk quite a bit, though.
So that's per photo library, not per photo. The rate per photo in their testing was 3 in 100 million, then they added a 30x safety margin and assumed it's actually 1 in a million.

To be fair though we do not know what the threshold is. But I would guess even higher than 5 — I would presume 12 or more.
I'm no criminologist (IANAC) but when you read about someone getting busted with child pornography they have hundreds or thousand of images — not one, not five. They're "trading cards" for these creeps.
(And yes, 90% of CSAM abusers are men, so y’all will have to find some other way to weaken my argument.)
