Those methods dont work for regular landings on tough coasts IMO
Releasing to the 5th is way too dramatical and not very predictable in high winds on rugged coastlines (and typically windsurfer fins on the beach straight up if not alone) - and releasing to a rear/front flag out line is the last of all that can be used at such places of course
And walking all the way up to the kite holding 1mm thin lines ?
No way I would do that at every single landing - it works yes, and we do it if stuck somewhere with no other alternative but that (or releasing to the safety), but it is way too hazardous holding these thin lines with your bare hands in so much wind at EVERY landing IMO.
Putting the kite LE down by tugging a frontline is a no-no at such tough surfaces, and you will most likely ruin your kite (or get a finger cut some day...)
Remember, we are talking high winds and rough coast where the kite can not lay on the beach without flying/sliding away - and you might also easily puncture your kite doing this, because of sharp rocks/shells/timber on the shore
If it were a sandy beach it is easy of course - but with sharp rocks or even small "not sharp" stones on the beach - the kite will get cut, or slide away and turn around immediately - it will not stay put for even 1 second as it is soooo low friction in the last case
The other thing is, it takes longer to "crawl" to your kite (or "Y") holding the thin lines, than just putting the kite on the stake and then walk or run or whatever you like, to your kite, to secure it on the beach with your board or find some soft rocks - or even better - move it away from the rocks to some place more safe
The other thing is - most of us want to go out again - and you can not self launch without the stake, in such places - so even if you succeded getting the kite down by a front line tug, without destroying it or have it slide and fly away - you can not launch by yourself again
Of course there is always a small risk to get a puncture at such spots, even when the kite sits on its edge - but it is minimal and happens so rare - compared to all other self land methods.
So the stake method is one of the most used, as it works almost everywhere.
But I agree, that learning ALL methods and using the right one where it fits, is by far the best option, true
Sometimes NONE of the self launch methods works very good really - and it is very risky - but one usually finds a way and take a chance (it is only your kite and not you) and succeed finally.
