Ultimately, no-one can be right all the time. In a world being forced in one direction against the natural flow of the will of the people like a massive cruise ship containing the government, it is highly unlikely it will turn on a dime.
It could with utter chaos, destroying the engine room is certainly one way. Those that hold power will not willingly give it up though. They did not get where they are with feelings for the common man (ironic though that is) or if they did, they have been brow-beaten in a forge of conformity to get along. The deaths of many protecting each side and those caught in the crossfire would be carnage. Much as I would like to see government 'switched off' and grab the popcorn to watch those with a suit and no life skills whatsoever beg on the streets, lets also look at another way....
On the other hand, we have someone who I am not totally convinced is legitimate but be that as it may, he is using the favored 'wedge' tactic to some degree. Turning the ship by a degree or 2. As governments do, he is nudging the tip of a wedge in a seemingly impenetrable door gap (like the regime constantly bringing up a 'cashless'society until years of defeat will turn to victory through repetition and new measures as they seek a way to make it so).
If he does not ruin the forward momentum, he may just be a pioneer for both volunteer/anarchist groups by creating a small opening, like the OP said ' planting the seed'. I'm aware of mixing metaphors here so lets get back to the ship scenario. He may very well fail, but although a ship may not be turned by a single wave, a constant beating by wave after wave even from different directions can rock the boat enough to seriously think about getting to the lifeboats.
Lets hope as said above, that tolerance of different plans toward the same goal can be accomplished (it is the same goal maybe with 10-20% difference that can be indulged at a later date). It really does not matter HOW it is achieved, but it is important a change is made whether small or big. Remember we have got here over lifetimes, and also remember there really are shades of grey ...... no-one can be right all the time.
