Actually, you basically just rephrased my point: the argument I was responding to applies to everything from mild dysfunction (inter-generational family addictions being passed down and celebrated) to perfectly benign (similar habits regarding board games instead of drugs).
Hence, it applying to teasing doesn't say anything at all about whether or not teasing is a good thing -- the argument applies to nearly anything at all, both functional and dysfunctional.
