So, an idea is without value without somebody to implement it? Really? Ideas are bought and sold all the time before implementation, so they have a value on their own by definition; a value set by the market.
Idealism is great, but there are bills to pay and food to buy. If there were a universal income, I would agree with you, but how does one make sure one gets a reward for an idea when somebody else implements it? And no, I don't get to dictate how people implement my ideas, but I do get to dictate if, when, and at what price people get to implement my ideas; they are mine, after all, and I have to eat. Patents may not be the best way to go about it, but ideas with value need some protection against the dishonest people out there when they are a person's source of income.
Beyond that: more generalities. You have learned other people's theories by heart well, but answering a concrete question seems to be beyond you. Why do you answer with a link to other people's theories in stead of doing some reasoning of your own?
