It is very common that one links money to survival, but I don't think it is presice. Money is a means to play intricate human games, and it is a very smart invention, so you don't need to have lots of cows and horses as a payment.
It is convenient to have money to do what you want, unless you are a slave of it and believe it is a means for survival, as if you will die without it.
In the modern world, your bank account goes minus when you don't have money, and you may receive some calls or letters from the bank trying to remind you about the game, that is all. You are still breathing.
The scariest thing is that your love and dream dies when you don't have the money to play the games conveniently.
And many chose to already kill their dreams way before the bank account is empty, because they believe a stable amount of money in their bank account coming every month will make their beings relax.
It is all in the mind, and mind is absurdly cunning making untrue stories to believe in.
