They don't need to break anything. They can simply compel you, and if you refuse or lie, you're held in contempt and go to prison until you comply.
See the fact that a stodgy old aristocrat wrote the defining book on this matter over a decade before the redditor class had their first epiphany on crypto.
The political class has unlimited funds for any youthful advisement needed for necessary corrections, assuming for a second that youth brings actual advantage. They have unlimited access to the smartest people, all who know what encryption and p2p is.
It couldn't matter less what mistakes they make when speaking publicly. They could communicate solely through pre-recordings of their farts and still have their way. For better or worse. The only actual arena in which the future will be decided, when and where it is actually contested at all, is that of bleeding-edge technical dominance.
I'd offer that they are less idealistic than are crypto-warriors, and therefore the bulk of the latter may not be well enough calculated in what they are wishing for. Yet, like I said, it seems that the argument ultimately will be settled in tech.
Now, what "the youth" not assume but know, is that public servants whose salary they pay via deductions from their own earned income, are hire to represent and serve the people. What they also know is that some of those hired servants think of themselves as rulers or "the ruling class."
It is very safe to assume that if an elected public Servant thinks of themselves as "the ruling class," that they are logically and morally wrong. No one assumes it's due to their age - that's a false narrative you made up so you could switch victim and attacker. Here in reality, "the youth" think those are immoral lowlife degenerates on a powertrip, at any age.
Now as far as "access to smart people" - orange mango had access to smart people. He ignored them all to kill a million, and told a quarter of the country to eat horse dewormer, malaria medicine, and use disinfectants like bleach, hand sanitizer, and.. and sunlight, inside of the body.
Do you often observe people who are not smart, listening to people who are, or is that only in the delusion you made up to be able to state a point? Here in the real world, mine and statistical observations are that the dumber someone is, the less they will listen to someone who knows what they're talking about.
Now, you realize those "crypto-warriors" you talk about have zero to do with encryption - right? Do you know what crypto currency is, and what encryption is? Do you know what "https" means in the URL you're on right now, which isn't letting a man in the middle change the comment I'm typing, or the comment you're viewing?
My favorite goto in these discussions - the Australian PM saying that the laws of Australia override the laws of mathematics, when talking about encryption. You heard that right an old bald guy who doesn't know how to use the second mouse button because mice don't have buttons - they have ears and a tail - is legislating to break AES256. You just have to pass a law to break it you see, and then the math law will have to obey the overriding Australian law.

Here's the thing though - that's not what this is all about, and these old hags have a very well-versed body of people behind them pushing the agenda. The reason the old hags sound like clowns, is because they are puppets with clown makeup. The goal here, is exactly what you said. Prohibition of encryption, because the people in power want more till they're kings, and they want to see everything you do so they can stay kings. In reality, none of this is meant to be enforced. It is however meant to pile up bogus charges and remove you from the public eye where you can make noise against them, once they decide to remove you for any other reason they want.
