for me, more things are automatic, not just roller shutters... otherwise, as you already wrote, they serve as:
Privacy protection
Burglary protection
Shading
Then you can save yourself the automation and keep them down all day - 24/7. Maybe open them now and then to peek outside
It's a bit off-topic here (but today everything is a bit chaotic anyway and it all comes together when it comes to electric roller shutters),
but statistically, burglaries happen more during the day, when you're not there - in exactly that one half hour. Shading only makes sense during the day, and in the evening you don't want to be seen.
We also have roller shutters on some windows on the ground floor, but I will hardly use them. I want to see the garden in the evening. Uninvited viewers are only on one side, unless the neighbor on the left and the neighbor on the right turn out to be peeping Toms, constantly hanging at their window to look at me. But I don't think we're that interesting
The seating area isn't planned to be visible, that's the advantage of building a house.
If I have a bad day, I close them. Yes. But in a cozy home, you also like to stroll around now and then and enjoy the individual rooms.
By the way, it's absolutely annoying when it's still relatively bright to look at a roller shutter... in our residential area, everyone now leaves those things up and has pleated blinds that at least allow them to see out at head height.
I think if you look at these aspects, you'll come to the realization that you can live without electric roller shutters too
