Government activities are generally important to a lot of people, if not because said people are direct consumers of the alleged benefits then because they paid for them. We keep paying and they keep ballsing it up, and everything we know about the theory of government (in an economic sense) tells us this is a design flaw and, ergo, not something that can be expected to self-resolve.
And it's not that they're totally inept all the time (although ineptitude is a recurring theme) - sometimes they do get good stuff done. The much harder question to answer in these cases is how efficient was it? How much tax money was shat away in admin/stupid compliance BS, and is all that wasteful pomp really a necessary price to pay for democracy? Could there be another way?
It's all very contentious, high-stakes stuff and if you disagree strongly enough with it all to wilfully not comply you'll soon find the whole system is propped up on various threats: they'll take your money, your home, your pride - they may even take you. And they'll do it all under a banner of moral righteousness that turns it into you vs. "society". How could that ever not be a talking point?
I talk about it most days in one way or another, and not because I'm some horrible right-wing fanatic who wants to wipe my ass with money and glee in the suffering of others, but because it's an incredibly fragile, wasteful system that perpetually sits on a knife edge and I suspect does just as much harm as good. It's misguided in so many ways and so, so hard to change that all I can do is moan about it and hope that my moans contribute in some way to getting the volume of the debate loud enough to think that something could change.
So, yeah, that's why I think it keeps coming up.
