It's not that Nama follows every rule. If she followed every rule, she wouldn't have ended up in this situation, because she wouldn't have convinced her husband to let her help him with his work offworld. But she follows the big rules. She listens to her husband. She doesn't talk to strange men (or anyone, these days, besides her husband and his brother and her infant son). She doesn't try to earn money for herself, even if she does keep an eye on which things she does affect her husband's bottom line. She doesn't wear clothes. And she may have left Ferenginar, but she never leaves their freighter, so if you think about it, it isn't really very different from spending all of your time inside a building on Ferenginar that you never happen to leave, which isn't very different from how her life was before her father leased her to her husband. None of these things have ever struck her as problems; they're just how life is.
She's not going to claim that her life was ever perfect. But she loves her husband, and she loves her baby, and she loves getting to do maintenance and repair work, and all in all she thinks her life is pretty good.
The pirates take over the ship in minutes. She spends most of the attack hiding in a closet, hushing her infant son, listening in on pirate communications and holding them up to a computer translator, which is how she finds out that her husband and his brother are dead. Then she sneaks to the secondary maintenance controls, fills most of the ship with poison gas, and fires on the pirates' ship before the remainder realize what's happened. The other ship has its shields down, probably to facilitate beaming over. The only sense in which it is not utterly destroyed is that she might be able to salvage some scrap metal or other materials, if she could find a way to access the wreckage.
Apart from her four-month-old infant, she is alone, billions of miles from the nearest other living being. Her own ship barely has enough power to maintain life support. But her cargo is intact, and she does have just enough power - if she can make the repairs quickly - to come within hailing distance of their intended destination, the Cardassian space station of Terok Nor. The shipment will be late, that is unavoidable, but it may be timely enough to trade for the help she will need to return to Ferenginar.
It is forbidden, of course, and if she does return, she will return in utter disgrace. It will involve talking to strange men, and earning profit, and wearing clothes, and setting foot inside structures that don't belong to Ferengi at all. And it requires a dozen skills that she does not possess - trade negotiations, acting, an ability to communicate in Cardassian beyond the few dozen words she's picked up in overheard conversations, any understanding of Cardassians as a people besides "torture" and "they do everything their leaders say" and "they care about family" -
But the alternative is death, and no Ferengi places dignity above life.
It takes her two days to get the ship limping in the correct direction at all. She fiddles with the replicators until she can get them to produce a set of prosthetic ears. She dons her husband's clothes. She tosses all of the bodies into space. She sets the computer to prepare to translate Cardassian to Ferengi (which will cause delays, since her computer can't do simultaneous translation and will need to translate and then play its translation in Ferengi, then do the reverse for her own speech - but she's hardly going to take the time to finish learning Cardassian.)
Then she slowly drifts towards Terok Nor, broadcasting a distress signal.
