The issue I have with this proposal is that politicians won't change their behavior. The optimum politician is an absolute pragmatist without any moral values. That is what you need to be to succeed in a federalistic democracy.
Regarding Chat Control: Do we know who is lobbying for it so much? Maybe journalists should focus on finding dirt on the lobbying organizations, so that everyone knows about them.

Their whole deal is to convince legislators that scanning every image on your device for CSAM is absolutely necessary (https://www.thorn.org/) and then selling a tool to do that to companies (https://safer.io/).
If it's legally required, what else are you gonna do but go to them for a "solution"?
