The sentiment of the above quote usually gets twisted into the "wide tires are faster than narrower tires" BS.
I know you don't care, but this has been tested before:
Wider is not necessarily faster - here they find the sweet spot for them is 32mm - but there's a combination of width, tire make and model, and pressure that's optimal in terms of mph/watt for any given rider and road, and unless you're 145 lbs, riding on new asphalt, it's probably not 23mm at 140.
But ride what you want. Just accept that it's a preference, not empirically faster.
