While I dislike many of Yuval Noah Harrari's politics, his book 21 Lessons For The 21st Century gives good insights for what's to come in the future.
One point he makes, is that authoritative states will evolve and take new forms that are hard to initially perceive as tyrant. For example, government today use authoritative measures through the guise of "inclusivity".
They enact hate speech laws that attack our language. They censor information rails, to attack our communication channels. They cut off banking access, to attack our financial safety.
Many aren't willing to admit our governments are tyrannical, because their fascist immune system isn't seeing gas chambers or gulags, because that's what they expect it to look like. They don't understand how these violent ideologies adapt and evolve to survive. Some know it and support it, but that's another discussion.
I don't think the enemies of freedom will kick the doors in, and take out the Bitcoin devs. They'll instead attack Bitcoin by controlling information, finances and language.
They'll continue pushing the ETF or to hold in exchanges, instead of taking self-custody. Good legal citizens don't need to hide anything, only criminals need to use UTXOs. If they can have Bitcoin turn into a shiny useless rock like gold, then it is no threat. Their goal will be to control the narrative as to what Bitcoin is: "It's only property, it's not and can't be a currency".
With their infinite money printer, they could attempt to buy all public mining companies. Slowly accumulate a majority of the hash power. Then, use their majority position to fork or control blocks.
With hate speech laws now being the norm, the next step could be to enact new "dangerous code" laws. With hacking becoming more prominent, I could easily see a push towards limiting what is permitted, when it comes to software.
Anyway, the point is, forget the gas chambers and gulags. Sure, these things could always happen, but it more likely they will attack Bitcoin through subtle means, that many won't be able to perceive as truly tyrannical.
