These free generators need to include some kind of audio watermark or key to indicate they are ai imitations. At least raise the barrier for this kind of action to being able to run your own llm or something.
It might be worth trying, but I'd bet that it's less than 6 months before running it locally means "download the app off the front page of your app store of choice".
Most criminals are lazy and/or not very tech savvy. Raising barriers and prosecuting the worst offenders cuts down on all sorts of malicious behavior that is technically feasible.
I think that would result in the average person being less aware of the capabilities existing and therefore being less prepared to defend against it. It isn't like this would be a world law that was universally enforced anyway.
We are never ready for the consequences of technology. We adjust to it long after it has been invented.
That is to say: I think this was inevitable.
What's the point of considering potential abuses if you're just going to facilitate them regardless? If anything that's worse than not considering abuse at all, because it implies that you know what you've created will result in kids killing themselves after fake nudes of them spread around their school, or enable rampant fraud and extortion through voice cloning, but you believe that's just the price of progress.
If so, that is easily provably wrong, unless you think there's an enormous conspiracy involving thousands of people to pretend that they're working on it when they really aren't.
This is a known and often repeated trend in tech: make something under the guise of disruption, with no regard for safety or regulations. Complain that those things are a hindrance to progress and then spend billions and destroy lives permanently to eventually fix the problems when the regulators issue an ultimatum that professionals warned you about.
I've seen wild swings in comments before based upon the time of day. E.g. mid-day upvotes, late day downvotes. Or vice versa.
