Who wants to be a member? Why would someone willingly join a community where they earn less (although most likely save more), work to others gain, have mandatory exercise, fixed diets and train continuously to improve themselves in a variety of disciplines and have a simple austere life (initially at least). Wouldn’t they desire work in a cutting-edge research lab or start-up company, earning a high salary and all the liberties and freedoms that entails and all the capital to eat, drink and do whatever and whenever they want.
Without doubt most people will fall into the second category, it is indeed hard to conceive for many wanting the alternative. For that reason alone it is likely that the community will probably not attract everyone but there is an argument for around 7 archetypes who may well decide that such a community is appealing, if not for a lifetime at least for a brief period of readjustment.
