I think this is a great nuance to point out.

My ideal home that I plan to create with my husband, will involve the following:

- Shared living spaces where we will jointly agree on how they are decorated and furnished

- A conservatory/art studio for me where I can keep all the aesthetic things I like that don't go with the shared aesthetic, where I can decorate it entirely as I like (ie Pre-Raphaelite art)

- A nerd room where he can keep all the aesthetic things he likes that don't go with the shared aesthetic (ie anime posters, action figures, geek memorabilia), where he can decorate it entirely as he likes

Having shared and personal living spaces allows for us to compromise while also not giving up our aesthetics and preferences. I have noticed that in many marriages the man doesn't have a say on how the home is decorated, and his favourite items stay out of sight if they don't match the wife's aesthetic. For example this happened with my dad. It's not that his wife demanded he put his record player away, or his dark wood furniture, but they just didn't go with her established creamy French artistic aesthetic. So he put them away of his own accord.

I think it's healthy to have our own spaces, just like it's healthy to have our own bank accounts while sharing a joint bank account for joint purchases and expenses, but making a rule that "no women allowed" or "no men allowed" in your space is pretty sexist. I wouldn't want to do that with my conservatory, or for my husband to do that with his nerd cave.
