You can reduce almost anything that way.
‘What is wrong with a surveillance balloon hovering over every city following all citizens and logging their activity? It’s no different to the police officer on the corner observing the public’.
It’s a matter of scale, efficiency and generality.
The scariest thing imaginable is a truly efficient government. Our system works because there is room for rebels and alternate ways of thinking and living to bubble into the whole polity.
Gay rights for example.
If the government had had the ability to monitor all homosexuals back when the laws were truly terrible - they’d all be in prison.
Runaway slaves? Same deal.
but, doesn't it depend upon what the government's doing?
if the government is efficiently preventing mining companies from pouring cyanide into waterways, regulating large Wall Street banks and building safe and ubiquitous mass transit to replace large swarms of polluting vehicles -- is that scarier than every other scary thing?
Murder and rape? Same deal.
I think it's perfectly correct to believe that the US government in its current state is pure shit for more than just the reasons you mentioned. But forced inefficiency sounds like a ridiculous way to go about fixing it.
If society takes issue with the laws, fix the laws. But having a law that relies on selective and inefficient enforcement is a stupid law.
Imagine trying to argue your point to the USA Founders, who seceded from the government they found oppressive.
When you can do things broadly and cheaply, you tend to do so just because you can. This is analogous to "data mining" in "big data", aka one major issue with modern science -- when you look at everything trying to identify basic patterns, you'll have a heck of a lot of false positives.
