Amazon's moat is massive vertical integration across multiple verticals, which they also leverage cross-vertical for e.g. promoting new services (say, their streaming service) and to gain business intelligence on a scale no startup can dream of (see: Amazon Basics).

You might—might—out-compete them in some niche they're overlooking, just picking up their crumbs, but you'd need stupid-high amounts of capital to take a real shot at them, high enough that there'd be no hope of a break-even exit if things don't go perfectly.

I'd call that a moat.

So you seem to agree that Jeff Bezos is doing some things right, since it's easy to get vertical integration wrong - looks at Japanese or South Korean conglomerates for plenty of evidence. Doesn't that handily disprove the "you didn't build that" POV?

Well, Amazon is actually too young to tell, Japanese conglomerates, while not being all dominating anymore, are doimg quite well. As do the Korean ones, e.g. Samsung.

Is the thing keeping some other person from building Not-Amazon (or a dozen companies that effectively, together, fill its entire role—potentially better, even) that Bezos is uniquely capable, or that the existence of Amazon makes trying to do it way, way riskier than when Bezos got started, no matter how good you are?

Other businesses get started and are very successful, somewhat often. Are all those successful business people just not going after Bezos because he's so much better at business than them that they cannot hope to succeed, or is it because the market is transformed by the existence of Amazon such that trying to take Amazon on is a bad use of capital?
