Unregulated capitalism places all of the power in the hands of the wealthy. Even with the amount of regulation in place, the last 4 decades has irrefutably proven that. The transfer of wealth from the bottom 95% to the top 5% has has been insane.
The only reason we need so much regulation is because people are garbage and if they can gain something for nothing, they will. You cannot consider the pure idea of capitalism without also considering the reality of human nature, that it is inherently going to create a pyramid scheme like situation where the top transfer power and wealth to themselves in the largest quantities they can, in spite of pesky things like laws and taxes.
I came here to say "none of them" because they all suck gigantic balls and I just use a NUC instead. I also just use unified remote on my phone to control it with a track pad keyboard as a back up.
