This is a good move. I teach a summer async remote course that's ending next week, but I'm giving all the students incompletes until they come back to campus and take an in-person exam the first week of classes. All homework is worth a marginal amount, and if they fail the final they fail the class.
I'm not going to spend my effort policing whether they're using AI or not in their class work because it's a losing battle. At the end of the day, they can either demonstrate mastery of the material at an exam or not. It makes the exams higher stakes, but that's where we are.
I'd never pay to have you as a teacher, I'm sorry. Maybe your move makes a sense for the reputation of your university's degree, but as a student willing to pay to learn remotely, I'd not accept to be treated like children.
I hope at least the homework is good prep for the exams, otherwise if its grade value is marginal there's little point from the PoV of a student that just needs to pass the class to take it seriously
