Joseph: although whether your questions really need answers are debatable, I foolishly will.
And if it makes you happy I’ll concede that if all a woman does is be on on the street day after day, she should probably re-examine her priorities (unless she’s homeless or it’s a danger for her to be at home ch”v. In which case she needs help.)
In the time of Chazal not much was known about mental health, and the current “yeridos haDoros” means people were emotionally stronger. Women for the most part worked hard physically at home, so despite being unaware about it, additional exercise likely wasn’t needed. Many homes has roofs and yards (where women spent time doing laundry, needlework etc.) and benefited from sunshine and fresh air without being “on the street”.
My caveat, which you foolishly claim is more exclusive than Halacha records, is based on something that was drilled into us as schoolgirls, and I guess you didn’t get that messsage in Yeshiva… It’s simple ״צניעות איז א געפיל״. So in all your literal research you forgot about the 5th Chelek of sh”a, otherwise known as common sense. It’s time you find a mentor to help you out on that front. Or find a different topic to troll about…
