> I get it, filing taxes could be easier but it isn't
No, I don't think you really get it. This isn't about taxes.
The problem is that a private corporation has corrupted the federal government to such an absurd extreme, that it has abdicated it's responsibility to it's own citizens. That's why this is such a big deal.
The fact that it happens to be manifesting through tax filing is a relevant detail, but not really the point specifically.
> What about on the scale of things that government is inefficient at
Again, you don't get it. The government is not inefficient. In fact, the government is so hyper-efficient at solving this problem, that private companies had to draft legislation outlawing the government from solving this problem, just to protect their inefficient lazy duopoly.
