I suggest reading the wikipedia article: https://en.wikipedia.org/wiki/Feminism_in_Russia#The_Revolution_and_Soviet_era
It's more complex than this. First, obviously the bank account thing is a myth. When people cite that women couldn't open a bank account, they're mostly referring to the date that a law was passed that prevented banks from discriminating against women. Plenty of banks were already doing business with women. The law just required all banks to do so. Hell, the first bank for women in the US was opened in 1879. It was still a very important victory to have anti-discrimination laws passed. But if a woman wanted to get a bank account in the 1950s or 1960s US, she could.

But more critically, as the article I linked notes, the Soviet Union was not a paradise for women's equality. Here's the polit bureau in 1975:
But beyond top leadership, the problems were more fundamental. Yes, the Soviets were an immense improvement over what came before in terms of women's liberation. But women's liberation in the USSR was never a cultural movement like it was in the US. The party opened up some career opportunities that were previously closed to women. And cosmonaut was a high-profile example. But in the 1970s, the Soviet Union had a higher gender pay gap than the US.
