The fact that it’s endogenous is a big advantage, you don’t need to rely on an oracle (decentralized or not) to adjudicate such a market.
There’s also a certain purity to it. If you’re looking at a “price” you’re benchmarking yourself against something else, it can be a bit self-defeating. When people say, 1 btc = 1 btc, 1 doge = 1 doge, that’s what they refer to.
