@eli I understand your reaction. I'm not entirely sure if I agree with but I understand where you're coming from.
I have a few qualms about the post but not about the laziness framing (which I agree is the stance he's assuming). Back when I was studying these sort of things my impression was that most great work was inspired by strife and sacrifice but actually created in the quiet times afterwards; in the times when the creator could have chosen instead to rest with family and friends (or go to the pub). So, I agree with him that the act of creation is only made possible by prioritising it over other activities.
The major omission in the post, IMO, isn't the assumed stance on laziness but the tacit acceptance of jealousy as a positive force for motivation. Indulging in jealousy to motivate yourself is toxic and will eat you up over time.
If you can't find genuine positive inspiration for creative work, it's healthier to indeed indulge in comfort instead.
It's the difference between creating because you want to be like others and creating because you genuinely have something to say.
My 2 cents :-)
