(Evan may design cryptosystems that can't scale to their technological promises, but his aptitude for designing economic systems that reward early investment is well off the charts).
This. He even leaves Vitalik in the rear mirror on that aspect. Simply a genius.
That said, I think the biggest genuine advantage of DASH is exactly the fact that it is a centralized token system, with all the efficiency advantages that come with it. There won't be year-long debates about block size, on Segwit or whatever. Next week, the Emperor decides (eh, I mean, the community votes), and that's it. Vitalik must be green with envy ! But this results in extremely efficient payment systems. DASH is Evan's Mastercard company, mimicking as a crypto.
And this might exactly be something the adoption market is waiting for, not caring about seigniorage, true privacy, distributed consensus and all that, but just a fast, efficient payment system of which there's a guy that solves problems as they come, and get insanely rich in doing so (a bit like Bill Gates back in the old days, with computers).
