I don't think you refuted the underlying point so much as gave cause to it. The idea isn't that simply stupid people rise to the top, it's that people who are capable of gaming a system without providing for or attending to the system they're deftly traversing are floated by their EQ/credentials/jargon straight over the corpses of the things they were actually meant to shepherd or build. I have seen this over and over again, and frankly managed to sometimes straddle the line enough to play along and be the beneficiary of this sort of corporate backchannel -- it's a very real, very human thing.

I've watched wildly incapable people bluff their way up a corporate ladder, fail over the course of two years in an elevated role, and then use that previous title to bluff their way into better positions elsewhere (and then leave those positions before they're totally found out to move on to somewhere else with a yet better title). I've watched people come out of McKinsey into the startup world, talk a major game -- they are the best conjurors of business fantasy at strat plannings and my god, those decks -- but then utterly fail to deliver for years only to end up with SVP roles at major companies on the "strength" of their backgrounds.

I get it: play the man, not the puck or whatever...but eventually somebody has to make sure the puck ends up in the fucking net and not sold off to buttress quarterly earnings.
