I do like the idea in general and feel there's a lot of room for improvement between the (VC / bootstrapping) extremes.
However, the middle path from the article presumes the existence of VCs willing to join you on that path. The article waves this away with:
> angel investors are generally more open to a 2-3x ROI
For a $1M round you'd need to find 10-20 such angels (assuming $50k-$100k average check size) willing to accept small upside, for which you'll have convince them there's commensurately smaller risk. This will probably mean you have some revenue and some sense of where PMF might lay or some kind of brand/pedigree.
Do not underestimate the value of YC brand and being able to present on Demo Day gives you. A random Jane from Ohio building her tech company would have a lot harder time finding those 10-20 angels, to put it mildly. I'd be more careful when extrapolating path-dependent success into a general strategy.
That said, my gut feeling is there's room for the next Paul Graham to fill that space - somehow.
