You're basing this on speculation as pre-Islamic Arabia is not very well known to us. Its not true that women became objects. As you yourself point out they had rights to inheritance and dowry, which meant they had basic property rights. They also had to consent to marriage, though admittedly in the case of virgins silence was considered consent.
Its also not true that they couldn't do business with men. There's plenty of research in the last few decades that have combed the Ottoman court records and have found that women were active economic agents. They inherited, sold, and bought property(both commercial and residential) as well as founded and managed trust funds known as
waqfs. The idea that because some Muslim women were segregated this meant they were completely disenfranchised is an Orientalist myth from early modern travel literature and its not even one that went uncontested in that period.
Lady Mary Wortley Montagu, a British woman who traveled to Istanbul in the 18th century, famously said that Turkish women have far more freedom than their English counterparts because of their rights of inheritance and property rights and she would know far better than the men because as a woman she actually had access to the harem.
There are many legit criticisms of Islam, you don't have to pull out make believe or outdated ones out of your ass.
