Darwinism perhaps.. I wouldn't be game. But then again a swimmer takes up approx 1-2 metre radius of space wheras a kiter (showing decent safety by stayin the distance of the lines) 25-50m radius.
So who is hogging the space then?
Kiters freak right out at the mere thought of being excluded from a few beaches but then expect swimmers to only enter the water in a handful of spots spanning mere metres on a long stretch of coast? Er.. How's that again? The traffic should be enough to deter most swimmers but most people in this world go through life with blinkers on really.

In a more serious answer to your Q? Gracey I reckon (as I have said many times) we should all be landing 50m south of the walkway instead of (conveniently for smoov pack up and exit)
at the walkway.
Why do we land there? Convenience/lazyness.
Why does the distant relative of Charly Darwin swim there? Convenience/lazyness.
We are all lookin for the same thing; a quick easy get in and out for our fav pastime.

Diff is
we are the hazard not our Darwinian friend.

Showing consideration and voluntarily moving our land spot 50m south would be a great step in fostering relations in the area I reckon. Most likely it would result in less freak-out moments that
may end in a complaint from Joe Public.
