PapaBrendan said..As far as I know, the purpose of developing kitesurfing is to integrate traditional kitesurfing into surfing, to increase dynamics and beauty. So what are the advantages of kitesurfing?

Actually, the kite wasn't invented to integrate kitesurfing into surfing.
kitesurfing is it's own legit sport, very different to surfing and wakeboarding, although it allows some integration into both these other sports.
kitesurfing is unique in that it incorporates flying and riding on water (or above it in the case of foiling) into the one sport. Kitesurfing is so diverse, it surpasses all others.
what other sport allows you to smash waves, jump 25m in the air with up to 20 sec flight time and then throw a wakestyle flip with handle pass all in the one session.
The best thing about kiteboarding is it's appeal to be so much, to so many through its diversity and simplicity.
