Having a virtual girlfriend is not selling toxic yoghurts, it doesn’t harm anyone, it’s like if you buy yoghurt and put in on a pizza… you can do want you want with the yoghurt like with the AI.
The important thing is keep the data safe, like the yoghurt that must not be expired when sold.
Despite what the free market religion has been telling for decades, we actually don't live in little parallel universes that don't affect each other. Even putting yoghurt on pizza has on effect on the world, not just the individual doing it. Not understanding this is what'll be the end of humanity. AI girl/boyfriends will have a huge effect on society, we should think hard before doing things like that. Slightly slower technological progress is not as disastrous as fast progress gone wrong.
