I think it can be done safely, it's what i've been doing for 14 y now, but i learned slowly step after step.
I fly with brand new kite, bar and lines every seasons.
I check my gear (preflight check) line, connexion, attachment points etc ... every session.
I Role my line every time i stop on the spot to avoid any possibility of somebody skiing on them.
I take a really good care of my equipment.
I'm attached directly to a climbing harness.
I don't fly in any wind i test it first by riding where i'm going to fly to see if i like it or not, i also pick my spot.
It still something dangerous to do for sure, but less than some riders doing some megaloops at 100 feet over flat water or piles of rocks.
Flying with a kite is not a fashion if you think it's too dangerous then don't do it .
Just my point of view.
