The law unfortunately is our best effort at drawing a clear line (i said, "best effort") between acceptable and unacceptable behaviour. I'm not sure there is any hypothetical legal system that could eliminate every one of these scam businesses. And I'm not sure there's a hypothetical education system that can prepare those who would be fools, enough to put the scammers out of business.
And I would be scared of a business ethics committee deciding which companies are allowed to run. It would be worse than the App Store.
