Um, a lot gets done without violence, including regime change. In fact, nothing swells the numbers of a movement like state brutality on peaceful protests, and that is amplified with the ubiquity of the cell-phone camera and the internet.

This is not to say a movement by violence is bad, just that it can detract sympathizers.

But don't worry, when the regime has to choose between giving up (say in the face of a general strike) and sending out the goons, they'll always choose the latter. No one tosses the One Ring into the fires of Mt. Doom. It's the same paradigm that leaves us with senile geriatrics unwilling to relinquish the power of office until it is pried from their cold, dead hands.

Usually, by then, the military has realized the regime is illegal and as luney as Aerys II Targaryen (The Mad King, who Jamie slew, SoIaF) and is willing to do the wet-work. By artillery if necessary.

Then again, destruction of property like burning the Waymo cabs, is a common necessity. That wasn't the act of rioters, but saboteurs. Waymos are snitches and have been reporting to ICE the location of targeted civilians.
