-Easier birth control: Make the egg into an omelette
-Relaxed child support laws: Requires deliberate decision to incubate the egg
-Clean packaged periods: Egg = No mess!
Although, there would be stories about partners hiding fertilized eggs: Instead of unplanned parenthood we would have unconsensual parenthood
There’s probably more nuances I am missing. But do discuss it in the comments.
The GOP would have you tried for murder if you didn’t incubate. I’m not sure why you think their stance of not allowing women control of their own bodies would change.
It did brush my mind as I’m still baffled about some abortion laws even if there’s no brain development. But if it was an egg, it would be hard to enforce it and some eggs aren’t fertilized. I bet someone would try to outlaw having a miscarriage if they could.
Considering some states are already doing criminal investigations around miscarriages, probably.
