Freganism is by definition parasitic. Without wasteful consumption, freganism wouldn't exist. It would just be stealing, or scrounging, or whatever. But throw in the wasteful consumption spin and suddenly those less glorious monickers fall by the wayside and you are a "fregan".

Mostly I find it very interesting that dumpster diving now has a banner that people can gather under and even - dare I say it - act haughty in the process! A form of Urban Survival at its best.
