You've misunderstood what I'm saying. I agree with you: timescales far below anything that provide any meaningful social value are an intrinsic figure of merit (usual definition: "often arbitrary-seeming number people compete over") of the market microstructure we have now.

I'm not saying the markets must function this way, only that they do, and it's not evidence of a giant conspiracy or grift that they do.

The rest of my comment suggests that while we could potentially quantize the markets, it doesn't seem like we have much to win from doing that, and, further, that it's likely that the problems we're trying to solve by doing that would persist.
