I find this kind of topic a bit difficult and far from any reality.
With perfect conditions everyone could (or not, we'll never know) achieve amazing things in any domain/sport. Considering pure physical abilities without the rest of life's constraints etc ... is completely unrealistic.
For having done some cross country skiing sport in competition (rather tough and demanding for the body) 10 years at a reasonable level I can say that the environment and financial conditions, most of all mental strength and will are as important as personal physical possibilities. Financial conditions because they buy you some peace of mind which is essential to succeed.
I know that much less gifted guys than others have been much more successful on the long term because of their perfect dedication and sacrifices to their sport i.e no parties, no girlfriend, no deviance from the goal whatsoever. Also because in many cases their family was here to support them and take away from them almost all the burden of real life.
A climber like others is a person before all with all it's aspects and speculating on how one could do in perfect conditions is pointless to me other than as a phylosophical debate of ideas, precisely because perfect conditions never exist, and even the best athletes quite often have to make compromises.
Perphaps why not thinking about: At what stage will you stop having pleasure climbing for too much training or sacrifices required over other things in your life ? That might be the real limit for most people, in my opinion.
Finally I would also say that the constant mediatic pressure on how others achieve big things in exceptional conditions is just wrong. Why would there be any standard level to reach, why would 7 something or 8a be a reference?
These grades just don't take into account all the rest: training time, personal abilities. But media take care of well occulting all that.
