I find that asymmetric/concentrated power in the appropriate (!) hands can lead to better results for most things. For instance, I'd rather put my money in a company where the CEO has the proper vision and considerable agency over one that is ruled by committee, like most tech titants. I wouldn't advocate for a regression to authoritary regimes, but I think they can stabilize and accelerate progression towards greater objectives as opposed to a segmented and elected political power which rules on a 4 (maybe 8) years "vision" (colored heavily by polls optimization), for example China or ex-Yugoslavia. Linux probably benefited greatly from having Linus. It can obviously go wrong (North Korea, too many kings to count, WeWork, Theranos..).

I think it's a good hedge for NASA to have this policy, they probably selected a good pick in the first place, and if it went wrong they could probably easily replace the position [source needed].
