Yeah, but
how do you exploit that capital without interacting with the human-only financial/employment systems?
You can hire humans for things over informal channels with no intermediary, but what do you do for reputation/accountability when said humans need to keep low enough volume to not interest the tax authorities?
I guess algorithmic trading on decentralized/anonymous bitcoin markets is one way to have no humans, if you can get the volatility low enough.
How do you exploit capital with (almost) no human involvement?
