Maybe I'm biased, but I actually think it's a pretty good definition, as definitions go. All of our narrow measures of human intelligence that we might be tempted to use - win at games, solve math problems, ace academic tests, dominate at programming competitions - are revealed as woefully insufficient as soon as an AI beats them but fails to generalize far beyond. But if you have an AI that can generate lots of revenue doing a wide variety of real work, then you've probably built something smart. Diverse revenue is a great metric.

> Would that be services generally provided by government?

Most services provided by governments are economically valuable, as they provide infrastructure that allow individual actors to perform better, increasing collective economic output. (For e.g. high-expenditure infrastructure it could be quite easily argued though that they are not economically profitable.)
