I totally agree with you on this. But you also have to look at the long term costs of their behavior. There is a difference between resale value decreasing and actual depreciation (55.2¢ a mile, per the tax code, as of 2012). The Uber driver is going to have to replace his car much faster, so his long term net income is lower than you seem to think. In addition, the risk of accident increases, and nobody pays for $0 deductible insurance, so those costs have to be factored into the estimate of the overall benefits enjoyed by the driver.
