Life reaches a balance. Most parasites don't kill their host and even if they do, they won't kill the whole population which would kill the parasite itself. Cancer does exactly that. It kills just one individual but can't spread to others so it destroys its whole basis of being (since it's not a parasite).
Capitalism is on its way to do exactly that. It spreads over the world, exploiting resources beyond repair and just moves on. It expects exponential growth for some reason and that isn't sustainable. Life doesn't do that.
You can disagree but don't call me illiterate. I'm trying to keep calm and civil but if you don't understand my points, maybe you are stupid, not me.
I made a graphic in paint because I didn't have any crayons for you.
Feel free to replace Total Universal Resources, for "Human health" when dealing with cancer. Works as is for capitalism. as it does for life. As per the point of the OP.
What about a straight line? Do you know anything about ecosystems? There are sustainable ecosystems, obviously not for eternity but for much longer than capitalism exists
What is the point? The original post talks about limitless for still the universe will end at some point so it's not eternity put "just" much longer than humans can imagine? That doesn't change anything about the capitalism critics of the original post OP makes fun of
