That's defeatist, although certainly what they'd like. The world is not the US.
Even if NSA captured and logged all internet traffic, they'd still only get a fraction of the information within without breaking all the encryption.
And even if they could break the crypto, the ability would only have any power if/when they acted on it. Which in turns reveals the capability to both normal people and other nation states.
The limitations aren't laws, it's the practical consequences.
Of course, having laws with actual teeth helps.
Ok?
So they use it when they feel like and not willy nilly? That doesnt change my perspective. They still have the ability to do it at will.
> when they feel like
No, when they can get away with it. When the pros for them outweigh the cons. And every person affects that calculation in some small way - by their tolerance to injustice, by their outspokenness, by their ability to detect it, by the probability of an employee becoming a whistleblower and even by people's willingness to punish bad actors extra-legally.

Yes and your neighbor has the ability to wait on your doorstep until you open and then slit your throat.
He generally doesn't because of internal safeguards (humans have evolved emotions like remorse, though not all of them feel it - see psychopathy/ASPD for details) and external safeguards (the state generally opposes people infringing its monopoly on violence but in the absence of a state, he would still risk being hunted down and tortured/killed as punishment by your relatives and friends).

I get what you're saying and I oppose dragnet surveillance but seeing things in pure black and white does not help.
