Sure, if you want to convert my argument into straw-man form to more effectively belittle it, that is a very effective way to do so.
A more accurate way to extend the analogy to transportation would be a company starting a free bus service for lower-income neighborhoods. All you have to do is link your grocery store rewards card and scan it every time you use the bus, which will authorize the company to access all your purchase data from that card.
You could very easily argue that this is a good thing, and perhaps at the outset it would be. But if it turns out that the company is doing something sleazy--rewards cards sometimes also encode personally-identifying information which could be used unethically, for example--then at that point a person's livelihood could very well depend on continuing to use that bus system, especially if the convenience of the system forced other free or low-cost alternatives to stop serving those neighborhoods.
In both of these cases (the IRS preparing your taxes and the company holding your personal information), the organization is not incentivized to do a good job. In fact, especially in the IRS case, the worse a job they do, the more tax money the government takes in.
