I didn't propose to reform Uber, and actually didn't make any policy recommendations at all. I engaged on the narrow question of whether some gig workers are being "taken advantage of", which GP claimed was essentially impossible since they have "free will", which I think is a simplistic philosophical / economic argument.

For specific policy, I would probably support something like a federal jobs guarantee, so employment is available to anyone who wants it that sets a wage floor in the labor market. Then those offering gig work will have to compete with that minimum wage floor. But it's really not my area of expertise.
