The Rambam writes ” She is not a prisoner who may not come and go.”
It seems to me that the miforshim talk about women not going to din Torah because of “kol kevudah…” it indicates that women were involved in disputes because they ere involved in busines. But because of their kovod, it wouldn’t pas for them to argue their case in front of a bais din. Just like the Rif who poskened that it’s not HONORABLE for a Chacham who’s HONOR is greater than a woman to be called to bes din. It’s obvious that we are talking about KOVOD-HONOR.
The lesson I take from this is not that women should be prisoners, rather it is not honorable to publisize oneself. One is showing kovod and respect to oneself when we act b’tznius.
