Animals don't even have a concept of (private) property

Try taking a lion of it's mate, and tell me they have no concept of property rights...

Self interest makes everything a 'for profit economy'.

If you look in the link down below you can see some examples of how ancient tribes would have social systems in place to mock those who even took large social credit for their hunting kills, let alone let them take resources from others who needed them.

Every civilization in the last 3500 years (agriculturally based economies) is based on resource accumulation.
Economies of exchange emerged. Capitalism.

capitalism took form and evolved in the industrial revolution a few hundred years ago. ....

Capitalism is the natural system of exchange, not a theory reliant on industrialization.
Ancient exchanges of ' let me have sex with you and I'll give you food' - is capitalism.

That's how long it's been around

A fundamental misunderstanding of the concept. Capitalism has nothing to do with money.
Intellect and ego combination can be a hard barrier to get around.
..this might help.

also the basis of capitalism is not cooperation, that's the basis of human society,

Society came after cooperation, not before. After voluntary exchanges.

Society is a symptom of the success of capitalism.
