I agree with everything you wrote. My post was meant to be a reaction to GP's post that implied tailgating to be equal with driving in a way that minifies cars cutting in front of you. I maintain that there is a sweet spot that is both safe as long as you're alert as well as keeps the traffic around you in sort of a steady state where everyone can just keep following. If you let the gap become larger, others will start cutting in - if you then have to use the breaks you basically rely on the guy behind you doing the right thing as well, thus increasing the risk of accidents.
