To profit under intellectual property constructs. As it stands, AI output is effectively in the public domain.

Given the cost of generating images/text/etc. is much lower when using an AI system, as compared to a human, this seems appropriate. The purpose of intellectual property is to encourage people to invest that time into creating works that benefit others. Perhaps there’s an argument for a shorter copyright period to cover the cost of the compute spent, but certainly one wouldn’t expect AI intellectual property to require a similar level of incentive to produce.

Probably unless it infringes on others' copyright as it does...
