You Dictating that they can't provide value is YOUR opinion. In a society in which you espoused no individual is valueless. Everyone can do something for someone else at anytime. Also in this said society every individual has vastly much more wealth as there is no state to coercivly extract nonsensical bullshit. So each had more to give and each family is much more wealthy in aggregate with the abilty to provide on their own to those that you believe are valueless.
