I won't pretend to be so knowledgeable about how so much CSAM is being created, but keep in mind, there are laws against distribution & mere possession, too. Revenge porn is an obvious thing to be mindful of in this context in addition to other types of distribution. Consent to create doesn't imply consent to distribute (probably even to cloud storage) & is completely immaterial to issues of possession if it ends up in some 3rd party's hands. So the scope goes way wider than you're letting on. If you're saying all of these these laws are being abused, like they exist primarily to punish a state senator's daughter's ex-boyfriend, I would ask for something to back that up.

Yes, poor and unprivileged children can't really defend themselves here, but this is the system working to find some legal mechanism to do what it can, as a more powerful force. Protecting people from exploitation is a good use of government. If this was shot down for legal reasons, OK, the system is working and I hope there is a way to expand protections that fits into our system.
