Will the world be free, if man is money free?

MEaning, absolute security, no more worries. IT is almost like communism.
But it seems so much like feudalism again.

Problem, is how will soceity run, people will not work in militray, doctor, gov’t , firefighters, policeman. When these people are not here, where is national security then? When you want to buy food, should the merchant just give it to you for free? What about marriages, for trading it for dangerous position, while, those who are not married will be free.

Final thought, guardians of plato’s republic will be born.
