Maybe not a necessity, but it's there much more often than not.
Everyone talks about destroying the system, but not nearly as much about the systems that are to be built in its place or how to transition between them without mass violence that is wanted and encouraged by accelerationists to take down the system. Sure, community self defence networks help, but you're still at the mercy of whatever shithead takes the reigns in the inevitable power vacuum. Especially if you can't make/keep a large enough coalition to keep everything from falling apart into everyone's personal fiefdom.
How are people supposed to solve these issues if they don't feel like the current system is beyond reform? Defending the status quo will bring us nowhere.
And "Just do something" is a shit take unless you can figure out how to solve the problems without the chaos caused by destroying the system with nothing to take it's place or to fill the vacuum left behind.
So many problems are exacerbated by well meaning people who want to 'just do something's with no concept of the consequences or the knock-on effects of their actions.
No, you're arguing for destroying the system and not commenting at all on the shit that I'm pointing out, so yeah, you're at 'do something' in my eyes. And between that and that I'm out of give a shit for this conversation, I'm out.
