Agreed.
Also, proving one’s hard drive contains CSAM is technically a little tricky. It’s not like your node and my node each have one big file called blockchain.db that hash to the same digest.
I was today years old when I learned there is an obfuscation key applied to the stored blockchain data on your node…I am assuming one can accomplish a cryptographic delete by deleting the obfuscation key…and anyone trying to prove your hard drive had CSAM on it would have to create it by using key and querying the database and crunching the numbers to make illegal numbers appear.
