I actually agree with Sced on this.. somehow the discussion got to be about destination-less timed training plans. Many road cyclists go out to ride a route.. eg. with a friend, club or solo. Finishing the route on a heavier bike, assuming you're expending the same avg wattage, will take longer, so more of a workout. If you're on a club ride, and you complete the club ride at whatever speed the ride leader goes, having done so on a heavier bike means your workout was greater than on a lighter bike.
You're free to be as wrong as he is. I have to be home in time for work in the morning, so those rides are time constrained. That can't be an especially rare situation - I know lots of people have to be back in time for work or family obligations, errands, etc. That may not apply to you, may not apply to him... but it's not a rare thing.
