Well considering you can get a pharmacist to write the prescription for it I don't see a problem. They can inform users of any risks or things they should avoid. They can also provide info in other options like an IUD.

I think there is a balance here. There is risk, so a discussion is required. But, the risk is medium, so a pharmacist can walk you through options.

TLDR is basically: Estrogen based pills have inherent risks that the regulatory boards believe require monitoring. Non estrogen pills could probably get nonprescription status but it would require an expensive trial process which the producers don't think is worth it.

Doctor knows your medical history and can review which one is best for you, since there is risk

Hot take: There should be some medical intervention for hormonal contraceptives. A lot of women are just flat out not told of the horrible side effects. If a doctor doesn't tell you, at least you can sue.
