The impossibility of the assured annihilation of data is true of all protocols for data retrieval so long as client nodes are free and able to copy the data retrieved.
It's why removal of illegal content from the internet has been an abysmal failure.
So do people with skeletons in the closet. Not saying you do, but right to be forgotten can infringe on other people's right to be well informed.
This is not a hypothetical. It has already happened.

Using CSAM to justify a law, is not a winning strategy.
It would be tedious but probably destroying all nodes. Which means IPFS is not compatible with RTBF.

That does leave state actors though.

How does IPFS deal with CSAM being published on it? Not saying it should detect CSAM, but once it is found, how does one go about having it removed? You use the same system to handle RTBF, and if you can't, then maybe a platform where it's literally impossible to delete something isn't a good idea (partly because undesirable content will ultimately outnumber legitimate content)?

If there's an internet where Facebook and Google can't spy on me, sign me up!
