No one is threatening your individualism, if you don't like other people and the concept of cooperative society you can always go and live in the forest alone. This is possible for every single human being on the planet but no one takes it.
Because this fake individualism generates its identity not on the rugged individualism of standing alone but taking advantage of all the resources, benefits and skills of millions in societal human cooperation and then stand apart merely to legitimize petty self interest and exploiting others without remorse. In essence all the benefits of cooperation but none of the responsibilities.
This is people like Vinod Khosla in a nutshell and if your society is full of such 'individuals' and legitimizes their ideology you have to consider whether you have a 'society' worth fighting for. What is the motivation? Because these kind of individuals do not believe in the larger good, only self interest.
