Right, this friction makes it much harder for a scammer to get away with saying something like, "wire me $10,000 right now or you won't see your child ever again!" as the potential victim is forced to wait 24 hours before they can install the scammer's malicious app, thus giving them time to think about it and/or call their trusted contacts.

The sheer arrogance that you think someone manipulated successfully will just re-think the situation and ask their friends/family. The naivety to assume all scammers are impulsive fools and don't do this for a living, as their primary line of work.

So Google's going to add some nonsense abstraction layer and when this fails to curb the problem after a 24 hour wait, it will be extended more maybe a week, and more information must be collected to release it. We all know how this goes.

Potencial victim's AI agents will wait patiently those 24 hours. In fact it may just wait exactly 24 hours and not one more second.
