The proper remedy for bad governance is to elect different public officials to represent you. Jury nullification is far too weak, even as tinfoil hats go. Sure it's a thing and it's not illegal. It's just silly and unstable, and it should never be depended upon by society to replace good legislation and executive power.

Besides the fact that this ruling was about free speech rights, not jury nullification. You can say all you want outside a courthouse as long as you're not disrupting the legal system or trying to sway a particular jury in a specific case.

"The proper remedy for bad governance is to elect different public officials to represent you."

After 4 years you can attempt to fix it. Though if the person who you elect actually tries to fix it there's a good chance they will be stopped by the courts from doing so.....

E.G. Let's say bad politician hires bad people who implement bad policies. New politician comes in and tries to fire bad people, they sue saying its political persecution and they haven't done anything wrong and haven't violated the standards of their job or their contract. Court upholds it. They continue implementing bad policies, to the point of snubbing their nose at the person who got elected. What is the remedy here?

One person, who is typically elected. And that's if federal authorities decide to not get involved.

If the whole community believes X is not a crime and willing to nullify the law as juries, certainly they will elect a prosecutor who thinks the same.

That's a drastic oversimplification. For one counterexample, consider a prosecutor who believes x but also y. The community agrees on x but not y and consider that a dealbreaker, so the prosecutor is not elected. And this doesn't include issues such as ease of voting and gerrymandering.

They will also elect legislators that will remove such laws.

Or subject to recall. Which is what just happened to San Francisco DA Chesa Boudin.

After the cops decided not to arrest, then blame Boudin for not prosecuting. Cops just hanging out watching the crimes.

Let's not turn it into a whole Boudin debate. He was recalled, which indicates some level of voter discontent with how he operated. I personally voted against recall, but it is what it is.

DAs and police are directly or indirectly answerable to the public. Court proceedings are generally public record. Elected local governments have authority over law enforcement. See the recent case (without judging it's merits) of Gov DeSantis suspending a DA who refused to enforce abortion bans.

To be fair, they tend to only nullify the crimes of the wealthy and well-connected.

Whataboutism

Pareto principle. Focus on something that matters and is actually happening instead of nonexistent hypotheticals.
