Yes, but it still should be read the context of a post civil war, post surrender, obvious to a blind man that there was a rebellion situation.
What is dangerous, IMHO, is attempting to apply this to January 6. Let’s say that I punch my mailman because he keeps bringing me bills. An argument could be made that I obstructed a constitutional function and that violence against mail carriers undermine our system of government and thus I gave “aid and comfort” to those who are actively trying to overthrow the government. Any act, large or small, could come under this prohibition, and under this lawsuit, could be decided by a single partisan judge. I can’t believe that is proper.
