But I also believe that your question is exactly what is bad about the situation. It is a total red herring to the issue at hand. Let me expand:
He should have pleaded guilty to the crimes, because it is in my opinion, that he did infact break current laws, and that 6 months + felony, is not life ending sentence, far from it.
Consider this:
I also believe the laws in which he broke shouldn't exist in the capacity as they do.
You can hold both the above beliefs, and when you do, it gives you power to make reform in an appropriate capacity.
I respect that you don't believe these laws are just. One such power that helps society push back against such laws is jury nullification - the right to for a jury to say "not guilty" regardless of what the law claims.
'Should you always plead guilty to crimes the Government accuses you of?'
Did you perhaps mean to ask:
'Should you always plead guilty to crimes the Government accuses you of, even when you believe you are right?'
Which is still a red herring because it doesn't address the issue:
Did Aaron truly believe he broke no current laws, or did he believe so strongly the laws were bullshit, so he shouldn't be prosecuted at all? (which means he still actually broke them)
For example, presumably Aaron's lawyers would argue that while Aaron did in fact use a fake name on a captive portal, but that doing so was not wire fraud.
Why should you abstain from arguing if your actions violated the law just because they have hard proof that you did in fact perform those actions?
Whoever, having devised or intending to devise any scheme or artifice to defraud, or for obtaining money or property by means of false or fraudulent pretenses, representations, or promises, transmits or causes to be transmitted by means of wire, radio, or television communication in interstate or foreign commerce, any writings, signs, signals, pictures, or sounds for the purpose of executing such scheme or artifice, shall be fined under this title or imprisoned not more than 20 years, or both.
JSTOR was in a different state. Swartz caused signals to be transmitted by wire for the purpose of an artifice to defraud. The indictment is specific and cites to statutory definitions of what constitutes criminal behavior.
As I've said over and over again in relation to copyright issues, maybe things like copyright infringement should not be considered crimes at all, but right now, they are. If the elements of a crime are defined as X, Y, and Z, and there's proof that someone engaged in X, Y, and Z, then that person has committed the crime n question. Now if you want to argue that the law in question is unconstitutional for some reason, that's fine, but that's something you do at appeal. the purpose of a trial Court is simply to establish whether a certain set of facts is true or not.
You would be remiss to not even attempt a defence of such a 'crime'.
For instance, the trespassing charges, supported by the surveillance video of him opening an unlocked closet used by the homeless to store their personal effects, were dropped. [1]

Look, I don't want to bash the poor guy for his idea that such material should be free. But plugging into other peoples' networks without permission and so on are criminal offences, and Swartz was educated enough to know this. If you look through the indictment (http://www.wired.com/images_blogs/threatlevel/2012/09/swartz...) it's very clear about which statutes were being broken. Boingboing is presenting it as if Swartz was some wide-eyed ingenue that didn't realize that anyone would consider his downloading a problem.
Good read, related to the cat-and-mouse game: http://www.usatoday.com/story/news/nation/2012/12/14/jailhou...
