It was legal and common to discriminate on the basis of sex in banking services until 1974. I actually don't see anything in your link that disputes that. It discusses some earlier milestones about women being able to own certain types of property.
Even if we quibble about the dates involved, we all understand that historically women have been marginalized, denied property, voting, and other rights, and that this was the status quo for millenia, right? And that that has lasting effects that continue in our society?
