No, it should be illegal, otherwise everything would get destroyed whenever someone is slightly destroyed. Illegality serves as a kind of filter so that when enough people risk jail or death for a cause, that's because they really had enough.

I haven't given that a lot of thought, and it feels weird to say, but maybe the opinion that an act should be done and should be illegal can be true at the same time.

When a citizen commits a crime, they messed up. When ten commit a crime, they messed up. When half the village destroys the chief's home, the chief messed up.

I think you've misunderstood. Such things are also illegal in France. But there are times you need to be prepared to break the law to bring about political change, eg if a government repeatedly demonstrates indifference to public concern.

Suppose you are living under very corrupt or autocratic governance, and you protest in the conventional way (marching, waving signs and banners and so on) bu the government simply ignores it, or slanders the protestors for having a different opinion. What do you do then?

Maybe in their eyes those are the less-violent alternatives than their other options.
