One could look at the progression of tricks on a nature vs nuture model.
Most people when they start skiing and snowboarding start spinning one way because that is comfortable. This is the natural way. Seeing as you cannot spin left and right at the same point in time you either choose to do a left to right spinning trick. Say your first 3 is a left, then that becomes your natural way of spinning because there is nothing in the past to say you have done anything different. I will repeat myself, this first spin is natural. When you choose to try and spin to the left for the first time after having done only right spins (1 right spin is enough) then this becomes a nurtured trick because it is formed after personal experiences you had with the natural spin.
You might say doing a 360 is not a natural thing we inherit but i argue that it is when you trace human activities to the beginning of time. Humans are born with survival instincts, surveil instincts include fight or flight. Humans have opposable thumbs so we can grasp things for example spears. Most weapons don't call for humans to be ambidextrous, spear throwers don't switch hands, archers don't switch hands and gunman don't switch hands without having to start from the beginning stages of learning their skill. Humans are either righty or lefty. If someone who wrote with their right hand for their entire life and then at 30 decided to write with their left it would be contrary to the ordinary course of nature (i.e. unnatural. When you said "by calling something un-natural, it is only setting limits for yourself." I disagree because the limit has been set the moment you chose to write with your left or right hand. When you do your first right 360 you have limited yourself in ever doing a left 360. Seeing as the majority of people do 100's of 360's before trying them the opposite way then trying the spin the opposite way is certainly contrary to the ordinary course of nature (i.e. unnatural).
Heres another proposition, say you do 100 right 360's then decide to work on your lefts 360's and do 101. Just because you now have more experience doing left 360's does not mean it is natural, you just nurtured something to trump your nature. But lets be real how many skiers do more natural spins than unnatural spins before they die.
This term unnatural/ natural distinguishes how far a rider has come down the path of progression.
You can never do an equal amount of left and right spins from the time you start to the time you die so you either do more unnatural spins which would means you are a progressor or you do more natural spins and are existing in your nature. By contrary to what you said Iberg labeling something unnatural and doing unnatural things more than natural measures progression.
Calling tricks left and right strips them of any personality. I think its important to know a riders starting point as in which direction they started spinning first so we can compare that knowledge to what tricks they do today, it is an important indicator.
If your playing someone in skate and your challenger calls a right cork 9 and you spin a left and can't do right cork 9's than the other guy will get that point. If he were to call a "natural cork 9" then there is a level playing field. This is where the label unnatural and natural is helpful. Im not saying you can't play the other way for that will lead to more progression but by labeling natural/ unnatural it is more helpful to set someone apart. If someone can do a unnatural cork 9 better than someones natural cork 9 that is impressive. If you do a right cork 9 better than someones right cork 9 it seems you are only a little bit better and are only 20 right cork 9's away from the guy not as good at right cork 9's. If you label unnatural vs natural you can see it took many more times to get that good.
people progress at different rates but i think the average person can agree that it takes many more times to beat someones natural with your unnatural than it does to beat someones right 9 with your right 9 because it doesn't show your real skill. But i like the term unnatural/ natural because it shows where the individual started.
Im interested to know what other people think but i like unnatural / natural.
