It's really a question of how time factors into your accounting. If you're spending 10 hours to make $50, then it's tough to claim that as a $50 profit unless your time is worth less than $5 an hour.
Of course there are cases in which your time is worth less than $5 an hour (you don't have any other prospects for making money). Or if you enjoy what you're doing it might only be 1 hour of "work" with 9 hours of enjoyment. The point is that completely ignoring time spent is just bad accounting.
