I see that mindset in mega-corps, but at the smallest of scales... one can wash a car or fix a bike and add value to (and thus grow) the system, which logically means it's not closed/finite.

I don't know what cancer has to do with a closed environment. More like a failed "ecosystem in a jar*.
The body of an organism is a closed environment. It can be seen as an ecosystem of lots of different cells that live with in this environment. Cancer is just a mutation that allows some cells to replicate and spread through their environment in uncontrolled fashion.
In abstraction, chemotherapy is the idea of "have you tried turning it off and on again" for the immune system.
Here I thought it was based on the fact that humans are the worst and it is best to harness what little you can lest they take everything.
It is the way we do it! :-P
