I wanted to be a princess when I was little.
Beautiful dresses, sparkly jewels, handsome prince, throne, nice music everywhere, eating anything you like, people being really respectful and bringing you anything you desire.
Nowadays I don't think I would like it - your life is no longer your own, you are a tool for the purposes of maintaining a patriarchal and anti-progressive institution, you can't socialise how you want, if you're unhappy I suspect you aren't cared for but have people trying to cover you up.
Little girls have a romanticised view that being a princess brings freedom to have and do whatever they want IMO. My view was strongly coloured by fairy stories, not Disney.
In real life, I think princesses are about the least free people there are
I like KM as much as it's possible to like someone I've only seen on telly, and I hope she can be happy and lead a fulfilling life.
