System trope is a shortcut. Shortcuts save time in building a scaffolding of ethos and logos. But as with any shortcuts, sometimes when doing a shortcut actually doesn't shorten the emotional connection between the author and the reader. That's when the system turns from a ordinary trope to the creatively bankrupt one, as the author doesn't realize the weight of this trope and actually hurts the story. So, yes, the system trope is creatively bankrupt when author uses it as a crutch for building ethos and logos, which burnt out reader rejects as the authorial intent, making the author fumble his persuasion.
