Capitalism is clearning having a moment atm but as far as I know nothing about capitalism demands permanent growth. Capitalism is about private ownership of the means of production (and a complicated system of laws that allow ownership of abstract concepts, like futures contracts). Its the people who always want more - usually the ones who already have the most, and this has been the case since the first kings.
Capitalism is about giving power to the people with the most capital. Obviously they will use that power to give themselves more capital. If not, their power will be taken away and given to people who did, since they'll have more capital. This is an inseparable part of the system of capitalism.
> Capitalism is about private ownership of the means of production
No, Capitalism is about Capital and it's multiplication. Means of production are just a tool for Capital to multiply.
If the way capitalism works is by responding to the excesses of a few with unbounded growth and destruction to meet that demand, isn't that also an issue with capitalism itself? Capitalism does not demand permanent growth if you only define it by private ownership of the means of production, but in reality, it seems like the supply and demand dynamics result in some extremely inefficient allocation in relation to the masses just so a few can have their riches and, apparently, their massive water-hogging datacenters for SOTA LLMs.
