Yes. Ultimately, the reason we should let people choose isn't to prevent people who would be bad parents from becoming parents. That's an issue that couldn't be solved directly, but could be indirectly addressed by providing comprehensive sex ed. The real reason we should let people choose is so people aren't forced to do or not do something they don't or do want. People may choose the wrong option for themselves and regret it, but outside forces aren't going to know what they want better than they will.

Magical thought experiments can often mislead, as ethics cannot exist outside of our uncertain, unmagical reality.
