Why we couldn't live without money. Think about it #3

Nowadays we are so accoutumed to the use of money that many people never had this question coming to mind. Why was money invented ? Some today feel  like it was a mistake : one of the most obvious part of money is that it creates inequality.

But it is still legit, and here is why : 

First of all, i will (once again) send back to my first article on the purpose of existence where i tried to show that the universal goal of life is growth. This is important because as this is the basis of my vision of the world, this is also the basis of my reasonment. 

If you imagine a world without money, there is 2 major ways we could choose : the first is to live simply, "surviving", that means fulfilling only natural needs (to eat, to sleep...). The other one is that humanity would keep striving for growth, and is to me the natural one.

In the first case, a society without seems feasible, but it would be very animal and anti-evolutive. No goal... Nothing to reach... No reason to live except life itself ? Not for me, but why not ? Some people fit to this. Even though it seems feasible, thinkable, doesn't it seem sad ?

Let's take the second case now. First we can notice is that it would need a lot of organization (opposite of freedom) ! Example : who would build the fisherman's house? An house is worth so much more than a fish ! Would the fisherman maybe fish for a whole year for the mason ? Who would feed the scientist ? Who would feed the dustman ? That would require... wait fuck ! Taxes... Here is why taxes are legit (in theory only dont burn me pls) And taxes require money. Imagine you want your sink fixed, but you are an electrician. If society works with trade of services/goods, you can find a plumber that needs to have a plug fixed...  But in the case no plumber needs to have a plug fixed, you can't have your sink fixed. With money, you can pay him so he would still fix the sink even if you can't offer him any service/goods he's interested in. Money is made to be the good that everyone is interested in. 

As always, let me know what you think ! I love to have opinions, different of mine or not !
