True, it wouldn't be 3 billion individuals claiming the benefit. Still the scale is so large that it would utterly bankrupt most companies to pay out for a single breach.
If the cost of disclosure was a dollar a user there's pretty much no way we'd see them voluntarily tell us they were hacked. We'd have to wait until the information got out some other way.
I think hehheh is saying that a policy like this would strongly encourage hiding breaches. No one would openly admit a breach if they knew it would kill the company. The net effect would be less transparency, not better security.
