I imagine such an ecosystem could exist for a short time, but the prevalence of parasitism also points out how viable it is as a kind of shortcut for life. Perhaps the more terrifying thing to consider is how many species were driven to extinction by parasites that were just a bit too aggressive in how they affected their host, which also would likely result in the parasite's extinction as well. Life isn't a happy numbers game by any means.
