Points 1 and 3 assume any government wouldn't choose to target people who had a specific document, I think this is a poor assumption. Hash fragility doesn't seem relevant if both the hashing algorithms and the target content are known to the government Point 2 and 5 I don't understand, could you expand on it? If the government produced manipulated CSAM that didn't exist in any other pre-manipulation form, how would the manipulation be detected? And supposing it were detected, would CSAM database holders choose not to add that image to their databases just because it was manipulated? If that were the case, it would give pedophiles a way to exempt their images from the database too. Point 4 is neutralized by the government demanding local human reviewers for phones located in their country. China already does this with iCloud, they could demand the same for the CSAM reviewers, then coerce those reviewers or simply select them for party loyalty in the first place.
