As I read Kalosyni, she is objecting to Lucretius listing these character traits as undesirable "in general" because she thinks that sounds too much like a Stoic.
Lucretius could also be considering the implications of PD-5:
“It is impossible to live a pleasant life without living wisely and honorably and justly, and it is impossible to live wisely and honorably and justly without living pleasantly.”
The list of vices could be examples of acts that would not be considered wise, honorable, or just in most situations. I found PD-5 to be a good way of prudently making choices that require what DeWitt referred to as “calculus of pleasure”.
Thanks, Kalosyni for this interesting question.
