The key point is that seizing someone's property needs to be costly. It's immensely problematic when violating someone's individual rights is not costly, and you can seize the money of tens of thousands of people with the stroke of a pen and the push of a button. The same argument applies to surveillance. If the FBI has reason to suspect a person of a crime, then they have the right to set up some surveillance apparatus to gather evidence against that person. But this is a costly endeavor and requires many manhours of work. But, if you can automatically surveil every person in the country, and run it all through machine learning to constantly monitor every single person, then that becomes an extremely dangerous slippery slope into an inescapable authoritarian state.
