Finance also has a ton of self-regulatory bodies, especially FINRA, which acts as a central arbiter of ugly behavior that isn't illegal. I won't sing their praises on the hills, but they do exist and they are effective at instilling a sense of fear. Taxis and hotels, and AirBNB and Uber do not have this.
Ah, great. I'm sure the DOGE youth have excellent opinions on maintaining market functionality and stability, from their vast experience of being libertarian teenagers.
