All else being equal I think it is a good thing. Aside from bitcoin, stablecoins have been an area that I've been bullish on for a couple years.
A lot of bitcoiners in developed markets say people shouldn't be interested in stablecoins, but when you ask people in developing countries with big double-digit inflation, they are more likely to want dollar stablecoins as part of their mix. They want something that can be held for 3 months without a ton of volatility.
I think Taro, and Lightning wallets that offer both stablecoin and bitcoin functionality, would be good for the network if implemented well.
