> 1. Uber is actually a higher cost/less efficient producer of urban car services than the taxi companies it has driven out of business

This doesn't seem to be true, given that in some countries you have taxi companies providing services through Uber, as well as their own ride hailing platforms.

> 2. Individual Uber drivers with limited capital cannot acquire, finance, maintain and insure vehicles more economically than Yellow Cab

I'm not sure this belief holds any truth as well. I mean, isn't the biggest cost associated with Yellow Cab the taxi medallion, which represents a +$80k additional charge over the vehicle?
