What a weird take.
I have way less relationship experience than most people my age because I've spent the past decade+ dealing with a series of health crises. In the meantime, I've been to therapy, done work on my boundaries and relationship expectations, earned two Master's degrees, and in general developed as a human being. I'd like to think I'm not completely useless when it comes to dating. I certainly enjoy my casual fwb situations perfectly well. When it comes to romance, I'm much more likely to get taken advantage of than to do anything harmful to someone else.
Plenty of people have a variety of different experiences for many reasons. Trauma, mental and physical health issues, caring for a sick or dying parent, to name a few.
Your take is myopic.
