I'm not going to dig up a link, but a number of people think your total productivity goes down (not just per-hour productivity, as I emphasized in my post). So if it's a strawman, it's a strawman with internet access and an HN account.
I think your personal experience matches mine - I'm more productive in my initial working hours (maybe discounting the first hour of getting in to it), and are less efficient in my later hours. But my total productivity goes up as I work more, at least up to around 80 hours/week. Whether or not that's good use of my time depends on how enjoyable the work is to me and what kind of non-work I'm coming home to that day.
I may also agree with your position on long hours being a bad idea "in the long-term", but I'd quibble with it the way it's worded. Periodically working long hours can be good for long term progress, but working long hours over an extended period of time leads to burn-out.
