I could get into things like (a) how most Uber drivers get to write off $0.575/mi as an expense when they actually only incur actual costs of $0.20/mi, (b) how contractors get to write off other things employees don't (like health insurance premiums), etc, but explaining those clearly in a single blog post is difficult.
Also, keep in mind this post completely ignores opportunity cost, which is arguably the most important aspect and one that is incredibly unique to each individual.
Not a ton know about smaller tricks, like writing off health insurance premiums (hence why people pay accountants).
We're trying to help with both at Zen99, e.g. with all of our free resources at www.tryzen99.com/learn
If you're just looking to make a bit of money, then sure -- working once a month during a surge pricing event is ideal. If you're looking to earn a living driving for uber, being an employee appears to be better.
In SF, minimum wage will be $15 by 2018, and indexed to cpi thereafter, further eroding the argument.
Also, as minimum wage increases, then those employee jobs become more appealing, so theoretically the market rate for contractors would also increase in order to keep it a viable option. Though don't forget other benefits; many drivers value the flexibility more than anything.

There are plenty of folks out there that are unable to work 8 contiguous hours. Perhaps they have children, school, or even a part-time job.
If a college student has free time, they can earn cash as a Uber driver, but when they have a final exam, they don't have to work a second. Traditional part-time jobs, like being a barista aren't that flexible, so the alternative may be having no income during college.
Technically, Uber is not "lying" here. They're just talking gross wages, before driving expenses. Cab salaries are lower because the cab companies assume some of the costs of driving and build them into the daily/weekly cab lease fee (keep in mind almost all taxi drivers are independent contractors in the US).
And agreed on your last point. The questions/issues are much larger than Uber, which we bring up at the end of the post. Why are these jobs appealing to people? Maybe they're indicative of more systemic problems, and we should focus our efforts on things like improving the US education system so that more individuals have access to higher paying jobs.
