Should unassisted births be illegal?

***To explain my question further: this does not include emergency circumstances where the baby is born before a medical professional arrives.***

Inspired by the free birth post below.

Unassisted birth (free birthing) is currently legal in the UK. The parent(s) cannot face any legal sanctions for declining medical assistance, no matter the circumstances. There is no obligation to accept medical care or treatment during childbirth and post natal, and cannot be compelled to accept care unless they lack the mental capacity to make their own decisions.

Note that it is illegal for a non professional to assume the role of a Dr or Midwife during labor and delivery (e.g. Monitor the heartbeat or check for dilation) Should a person choose to free birth, their partner(s) should only provide support or face a £5,000 fine.

Bonus question:

Some medical professionals feel that this raises a safeguarding or child protection issue, and may report them to Social Services. (CPS) Do you agree with this?
