As usual, the economist is looking for its keys under the lamppost. In their graph, "Ease of starting a business" is a measure of how long it takes to process incorporation and tax paperwork. That is not the hard part. The hard part is finding co-founders and investors willing to invest, and customers willing to buy from new companies. It's a function of optimism and risk taking, not on government procedures.
We focus on the latter part because as startup junkies we're interested in that. But there are lots of low risk businesses which do not require partners and such. Running a hot-dog stand at the park, starting a small-engine repair service, doing horse-grooming, running an ice-cream truck. Sure, these things require optimism and capital (to some small degree), but you can get ramen-profitable with a bubble-gum vending company without partners or investors or any of the other stuff we talk about for technology startups.
What you can't get away from, however, is dealing with government at all of its levels.
