It does suggest, however, that a slippery-slope argument of "More surveillance plunges us immediately into a 1984-esque dystopia" has a big [citation needed] banner hovering over it though.
So no I do not think it is "slippery slope" at all, we have already slide down the slope; arriving at the bottom. We long ago surpassed the level of government surveillance I believe is ethical, constitutional, or proper for government
if the government having a database filled with everyone Bio metric data they can then use technology to follow, trace, and monitory your every movement is not a "surveillance state" I shutter to think what it would take for you to classify such as system? a Brian implant that reads your every thought?
(... I don't actually think it's a 1984 dystopia, mind ;) ).
I am sure there were many in Oceania perfectly content with their life, thinking they were free because they never butted up against the edges of their cage, they never tested the limits of their "freedom", they were "respectable" citizens doing as the government said
I do not recall getting that impression when I read 1984. Rather, the majority of the proles were absolutely under the figurative boot, and kept there via fear. Even the Inner Party were aware of the edges of their cage -- either they tested them and got reconditioned, or they were all-in on the dystopia, but I don't think that counts as thinking that they were free. Rather, they traded freedom for power over others.
To stay in dystopian sci-fi: The computers on the Enterprise (TNG at least) were aware of crewmember's positions and health situation at all times as long as they were aboard ship. Do we imagine they felt spied upon? It seems instead being born into a world where surveillance is ubiquitous and benign-to-benevolent, they were fine with it.
Maybe we can build that world instead of assuming the end-result is 1984 every time.
The Key difference between the 2 is Resource Limitation.
In 1984 Society had limited resources, in Star Trek it was a Post Scarcity Civilization.
Star Trek is not possible while we have limited resources, invent replicator tech then you might have the ability to create a Star Trek society, no replicators no Star Trek
This is akin to saying "humans on board the IIS are monitored intensely, do they feel spied upon? Therefore we should all be willing and able to live for a lifetime with that level of monitoring".
And not taking into account that IIS visits are undertaken by very unusual, pre-selected people, for limited durations, being monitored by a single organization, mostly for the purposes of research and protecting their investment.
Which is completely not anything like reality for most people, where things are operated by goodness knows who, for goodness knows what reasons, and barely or not at all regulated against potential abuse.
Keep believing the government has no access to this data..
That assumes 2 things
1. that the Warrant process today is more than a superficial formality to give people the illusion of check on government power. When in reality to get a warrant they simply have to fill out a form, there is hardly ever any push back and it has been proven countless times that law enforcement lies via omission, or stretched the truth, or any number of dishonest unethical things to get warrants, on top of the fact the most judges simply approve 99.9% of all warrant applications. "Getting a warrant" should not be viewed as some panacea of government restraint
2. Assume that "if they got a warrant" then people like me would approve of government having access to that data. That "Getting a warrant" is a valid justification for obtaining data.
