> as a vote that the price being transacted is close to accurate

These votes are not an indication of accuracy though are they? they are gambles about future price discovery. As in they don't care if they think the trade is worth $5 if they think it might go up before crashing to what they really think it is worth.

I'm not very knowledgable about HFT so I'm just trying to reason about how it works. I guess it's the concept that without the higher frequency everything must be more unstable which is hard to grasp. It reads like we have to make it easier for these firms to make more money so everyone else can enjoy the 3rd order effects of the process.
