Some good questions. Just some thoughts off the top of my head...We try to avoid eclectism here on the forum because it helps us focus and hone in on the actual teachings of Epicurus. Some background (and a reminder)...On our new user page, it states:
Thank You For Visiting EpicureanFriends ...
This is the place to study and discuss Epicurus with people who support and promote classical Epicurean philosophy. There are many places on the internet where other philosophies can be studied, but few are dedicated exclusively to Epicurus. We are the home for classical Epicurean philosophy, unadulterated by Stoicism, Platonism, or Eclecticism.
Many people take bits and pieces of neo-Epicureanism - asceticism, "enjoying cheese", simple pleasures but ignore the entire corpus left behind and being spoke about today, missing the entire reason Epicurus spoke about pleasure to begin with.
I would blame the "enjoying cheese" aspect on the small "e" epicurean food movement. And I would blame the idea of Epicurean ascetisism on academics who prefer Stoicism.
So what is the danger or benefit to people committed to saying "Epicurus was more or less right about everything related to living and nature"?
I think that is a vague statement, so anyone who might say likely hasn't spent much time studying the philosophy. Epicurus lived in a time before modern science and modern psychology, so there are aspects of these that we as modern people can use now. Epicureanism isn't a religion, but it is a philosophical worldview. And I agree with Cassius when he said:
But having said that, there is a general issue that everyone faces of putting together one's own life from whatever elements are available, and it's great to discuss in general how to go about thinking of the meaning of consistency and when fo deviate from it.
I would say that the two main aspects of Epicurean philosophy is the materialist worldview and its telos. If you can't agree with those two things, then you are either "not Epicurean" or you are "eclectic". But there isn't anything that says you have to declare yourself an Epicurean to benefit from the philosophy.
There may be some individuals who feel that they need some "supernatural" or "mystical" ideas in there thoughts and their worldview. This would be inconsistent with a materialist understanding of life.
The dangers of eclecticism is losing track of what was actually taught by Epicurus, or claiming that Epicurus said something that he did not say.
