This surgery along other cosmetic surgeries help people to choose their bodies.
IMHO nobody should be forced to live in a certain body just because he/she was born with certain genes.
If CLL becomes mainstream and cheaper, a lot of people dissatisfied with their height will be able to change it. Don't worry about "height wars", most of people will settle around 6' - 6'2'' (183-187 cm), because if you are too tall you will start having more troubles than advantages (just like the distance between atoms, where there is a balance between attraction and repulsion), maybe some people will try to do something extreme, but that it's not my cup of tea. The majority of the society will be happier.
Don't fear CLL becoming mainstream, it will improve the procedure, it would be more safe, easier, less stigmatizated and cheaper. Height dissatisfaction is bad, and "get therapy", "buy insoles", "go to the gym" or other "tricks" don't work if you suffer a true height dissatisfaction.
