They should be punished to the full extent of the law.
In the meantime, people who continuously talk about insurrection seem to be living in a fantasy land. Just as you say, without the military the "insurrection" means nothing.
Not lost on me that the government these people are claiming needs to be overthrown violently because it's tyrannical is treating them with kid gloves compared to most governments. And frankly the relatives of those that stepped over the line and will go to prison should be really happy they live in the US and not another country where people get punished because of mere association. Because that's totally a thing in other countries. But not here.
