> now its an internally contradictory horrible law because apparently it isn't important enough to consistently enforce

Law is not an abstract code, but an incremental sometimes futile approach to shape society. They only want a way to hold big corporations accountable to exploiting children. They don't actually intend the effects on the consumer, so they tried to fix on easily changeable effect: "Don't worsen the privacy for people who want it." If you are using e.g. MS Windows, you have given up everything already. They do a lot of "telemetry" and for example everything you typed into MS Word is already licensed to Microsoft.
