I think this is the point though @Marshtit.
When we see posts from women now saying “childcare would barely be covered by my pay”, we should encourage them to think longer term. Yes, childcare is expensive and will eat up most of your take home pay, but you will also be building up pension, experience, NI contributions, etc etc.
If - like you - they choose to step back from work, with this knowledge and ‘no regrets’, great. But if they haven’t considered the longer term implications, or not discussed them with their partner, topped up pensions, etc, then that is problematic.
