I agree with you but I think the key point here is "go home tired and then actually sleep" which is not often the case. After a stressful day as a software engineer or other white collar job, your body is not tired. Mentally you might be tired but that just leads to doomscrolling and social media and other dopamine hits. The key point here is that one should ideally be physically tired so that after they go home they want to sleep. This is why, for example, after a stressful day I make my body tired with a long run.
