Why do we need GDP growth? Is there no other point on the spectrum which is sustainable?

E.g. instead of “grow” - which is inherently unsustainable, you run out of materials and labour to feed the economy - i mean we can continue to kick the can down the road for a few generations yet and pretend we don’t understand what “grow” means in the context of finite resources. Instead of “shrink” which is also unsustainable. Is there some other viable point?

Because that’s why our money is worth anything in the first place. Unless you’re trying to make arcade tokens worthless outside of the arcade.

>> Because that’s why our money is worth anything in the first place

The reason most currencies are worth anything are because you get thrown in jail if you fail to pay tax levied upon you denominated in that currency.

No, money is worth something because another country wants to buy stuff you make and this must be done in your currency. Stop making what people want, or keep devaluing your money to the point where holding it means you lose value, and people stop using your currency. They become arcade tokens that only have value inside the borders. You cannot force value, economics 101.
