> That sounds like an argument for anarchism.

Fundamentally impossible. Power structures are inherent to all human social activity. Even if we instantaneously abolished all governments and all power structures, new ones would spontaneously form immediately after.

> I am very unimpressed by political philosophies that take arguments to their logical conclusion.

People's inability or unwillingness to take things to their logical conclusion is why mainstream political philosophy is doomed to fail. If you want to test principles, then you must assign extreme values to all variables and see how the system copes. Everybody breaks under this simple test.

> we should carefully design laws and processes to constrain it

Those already exist and are routinely ignored. The US government routinely disregards the rights of its own citizens, and nothing happens, all it has to do is say the magic words "national security" and it all goes away. Every once in a while, evidence of abuses somehow surface and they are so egregious that they have no choice but to do something about it, but due to survivorship bias you must assume the abuse is far more prevalent than what you're actually seeing.

Only structural solutions meaningfully change this calculus. It must be impossible for the government to abuse you in any way. Anything short of that will fail.
