I think ultimately I&#x27;m just not being clear about something I&#x27;m not certain of in any case, but a better restatement of my position might be:<p>&quot;Having some participants whose primary competitive edge is speed is not in and of itself bad, but speed advantages tend to consolidate around a few natural monopolies, which is.  So if we could add something else into the mix that allows for other participants to compete outside of those monopolies, that is good. Dramatically reduced tick sizes would do that, would at times make the spreads smaller, and might even make market making less risky systematically and doesn&#x27;t seem to have the downsides of other options proposed&quot;.
