Every step of the way so far useful idiots have come out of the woodwork to defend each and every incremental encroachment on our rights using some sort of tortured logic that uses some mumbo jumbo about common good to justify it while downplaying the danger and over-selling the benefit.
The weapons grade irony here is that, either by satire and sarcasm or by genuinely being that stupid you have gone too far, to the point of absurdity, you have (perhaps intentionally, perhaps unwittingly) distilled these stupid people's stupid belief down to basically one sentence "the slippery slope isn't real and everything is fine because we have a piece of paper" and when you lay it out like that it's obvious that that is a belief nobody who's got a couple brain cells to rub together would hold.
A piece of paper means nothing if people don't want it to and we will slide down the slippery slope unless there's a force stopping us.
