What is stopping you from lifting super light weight

If your bench is 200lbs regularly, why not dial that back to 80lbs and decrease the speed of your reps, decrease time between sets, and increase number of sets?

What is stopping you from having roughly the same muscle gains with none of the short and long term injury risks?

Has anyone considered this or are you all stuck on stupid still hoping you'll be the strongest guy in America someday?
