And I struggle to find a legitimate use case for being required to share anything whatsoever with any authority without a court order. There is a huge difference between sharing the details of your finances with a tax or other authority by default and them being able to compel you to provide such information if they have good cause to believe (and convince a court) that you are evading taxes. The fact the government required six illegitimate things of me before breakfast does not make them legitimate, it just means the abuse has become normalised to the point that people start believing this shit is reasonable.
