You seem to be confused between principally defending everyone having the same rights vs defending everything anyone can do.
The ACLU defends Nazi’s rights because they believe Nazis should have the same rights as everyone else irrespective of who they are.
That doesn’t mean they defend every possible action that can be considered a civil liberty.
Eliminating traffic laws would make individuals more free in a literal sense, but those rules also make it so people can get from place to place quickly and safely. The liberty interpretation is that what people actually want is to travel, not to drive however they like. So you trade a freedom most people don't miss to enable another.
Vaccine mandates are a great example of this contention where under normal circumstances nobody cares about having to get vaccinated but they do care about not getting polio. Covid was strange in that the number of people opposed was significantly larger than I think anyone expected.
It always seemed to me that the US was fuzzy when the very clear text of the Constitution rubbed up against the realities of a complex State. For example,
- the 1st Amendment doesnt say the speech can be overridden by a compelling national security interest, which is the argument here. But the US has security services, and legitimately there are cases where to allow speech does harm. But if you are going to be honest, shouldnt there be an amendment giving the State an override of 1A?
- 2A is infamous, of course, and for the love of $deity lets not discuss it here, but why does "not abridged" get overriden by bans in, say, machine guns, which have been on the books since the Chicago gangster era? Either you abridge or not. Or at least be honest about it .
- Some speakers in the covid era made a very strong appeal to personal bodily autonomy when it came to vaccine mandates. Ok, let's follow that. Does it not then also follow that a woman cannot be forced to carry a baby to term? That would seem logical, but the connection is not made. Conversely there is no "commonweal" override written into the Constitution and we are left with random SCOTUS decisions over the last 240 years.
No it isn't. The argument here is that it isn't a restriction on speech at all.
The courts have various categories for how important something needs to be to allow certain levels of unconstitutionality, eg suppose I have "legally" built the nuclear device featured in a recent kurgesatz video with enough kiloton to start by itself a nuclear winter kill every person on the planet... I seriously suspect SCOTUS will be ok with the state taking the ignition keys away from me
In September 2021, the ACLU wrote a New York Times op-ed defending vaccine requirements, arguing they actually advance civil liberties by protecting the most vulnerable and allowing more people to safely participate in public life. David Cole and Daniel Mach, the authors, wrote that individual liberty isn't absolute when it puts others at risk.
Surely, one can be pro vaccine mandates. But I would not expect a civil liberties organization to hold this position.

Requiring inoculation/vaccination, shut downs, masks, and quarantines was generally considered a legitimate use of state power to prevent the spread of deadly diseases and not an infringement of civil liberties.
Actually this goes back to even before the US was founded. George Washington imposed mandatory smallpox inoculation on his army during the revolution. This probably contributed significantly to his victory because both the British army and native tribes that had sided with the British were heavily weakened by smallpox but Washington's was not due to that inoculation requirement.
There may have been isolated examples in the past, but the degree was not the same.
I am personally happy with vaccine requirements, but IMO the ACLU should have been defending the people who weren't.
There is "freedom to" and "Freedom from" lots of people not getting vaccinated affects people's freedom from getting infected.
In cases from "Roe vs Wade" to "Masterpiece Cakeshop" and "Hobby Lobby" the ACLU came out against things supported by the religious right. And although the ACLU regularly supports the free speech rights of swastika-tattoed nazis - Republicans don't see that as supporting their side, because no reasonable person wants to think people with swastika tattoos are on their side.
