Yes. There won't be some peaceful transition to anything.
Bertrand Russell wrote any interesting book examining Socialism, Anarchism and Syndicalism called: "Roads to Freedom: Socialism, Anarchism, Syndicalism." It was written in 1918, so certainly a lot has changed, but his examining of the pros and cons of each, I think, is still valid.
The book:

A lot of people on the Left, further left, seem to have these responses of like "democracy doesn't work" or "doesn't exist," "we need to destroy/bring down the system."
It's certainly true we have some limited form of democracy, at least currently exercised, where people occasionally pull the levers every couple years and go back and forth in with political parties.
Though this isn't ideal, or a good thing, I don't think we should throw the baby out with the bathwater. The way people seem to act - apathetic, or distracted by personal pursuits - one of the genius aspects of capitalism (in a negative sense) - doesn't necessarily mean that is how society or democracy always will be or has been.
Regarding authority. I was having a discussion with an acquaintance who was adamant about communism as a viable alternative to capitalism and he also had a pretty contemptuous view of the police. He lumped them all together as a group/class serving those in power.
I certainly agree police can be corrupt, racist, abusive, etc. but I don't think all cops are bad, nor that every protestor is innocent/non-provoking and law-abiding.
Thinking we will have a society without cops is a little ridiculous. It's easy to muse about in some idealist sense and say "if only X, things we be ok." There are some fucked up people out there - yes, you can argue that includes cops, and it's true - we have to have some kind of force that can handle those that seek to do others harm. Of course when the harm is switching water supplies for a city and causing people to die of lead poisoning, those people seem to be immune from punishment.
I don't trust the dissolution of police forces and leaving "the people" to dispense judgment - even if we still have a constitution. People seem to easily fall into fascistic thinking and behavior.
