The coming war on general computation
Psst kid. I will give you ten teraflop hours on my rig. Though more seriously I wonder if history will if not repeat then rhyme when it comes to encryption (we already saw some forays there when various things like telegram started to pick up, if someone actually does a proper service then wait for the fallout on that one).
So yeah as computation gets to have some serious implications, and possibly 3d printing starts getting into serious plastics, metals, ceramics and more by those in the hobbyist/guy in a shed, never mind those playing with serious chemistry on that front. That will probably be attacked. Whether it will be barn door after the horse has bolted, or live on underground I don't know. Whether it will be weapon control or patent holders that go in hard first I don't know either but I imagine both will be present (whether unholy alliance I don't know).
Psst kid my 3d printer does hardened steel and does not have a DRM chip in it.
Anyway outright illegal is harder. Most things end up more restrictive (see what you can and can not drive on tickets from different points in time, and how much harder things get made) but that is usually more of a money spinner than illegal.
It would also depend what sort of government gets in and what their opinions on rights and freedoms are; some kind of crazy environmentalist types, resurgence in old school religious thought (debatable, though they are the only ones breeding at more than replacement rate), ascendancy of the respect my pronouns or have your collar felt set (or their lesser cousins in harms is the absolute worst thing that can happen set therefore my risk tolerance is world of cotton wool)... that could change things radically, and has done when various such things arise in places. The huge variability across what are nominally similar countries (compare the various parts of the UK, US, Canada, Australia, New Zealand... for how different that plays out and more are the same genetic stock and shared legal history/philosophy until... I have books older than the splits there).
Curious to see the fate of tobacco. Various places have banned it, all but banned it, had interesting "if you are born after this date then not for you" debates (see Russia for that one). If the various "take this pill and you will stop" gets ironed out more then that will be better still. There is however going to be serious money opposing that one.
Related to the money spinner I am also awaiting the fights between environmental types, consumer rights, health and safety, insurance, basically guilds and more as it pertains to building things; very hard to buy a bit of land and do what you like with it, some places you can't fix your own car on your own driveway, reclaimed timber is tricky to use in buildings right now, own milled timber might need a test to be used in a building, technically speaking I can design and check install of a setup measured in kilovolts on an industrial machine but if one of the bank of plugs behind my monitor goes I am not allowed to replace it, some of the things I am seeing car makers do beyond that... things related to all that will probably be a fun field in the future.
Though on cars then when AI becomes better than humans at driving will it in turn be made illegal for humans to drive outside of maybe a dedicated track?

Cybernetics and biomodding. "My body, my choice" could get tested here when nerve attachment or brain reading options get better.
On drugs then some have pondered if we get proper notropics (makes you smarter drugs) what will happen then; as it stands some university types have suggested piss testing people for ADD meds. Couple that with "the encyclopaedia is literally part of my brain, can't disable it" from the previous bit.
