I mean you can't really replace the government with corporations if there's still a government. Especially if you want to do things like start your own corporate run cities and tyrannies/monarchies/fifedoms as so many of these guys have discussed.
That's the Curtis Yarvin techbro plan right? Roll back to before the French revolution. Taxation without representation.
They haven't worked since all becoming for profit, rather than for... dating. Turns out setting people up should really be charity work, not for profit.
No, the joke you're making is about Anonymous, and the authorities trying to find the leader of them.
Antifa (Antifaschistische Aktion, Anti Fascism) on the other has and will periodically form into local chapters (usually out of members of other more permanent anarchist, communist, and protest groups), to participate in protests, produce things like stickers or book drives, run pop-up or community libraries, events and form other organizational structures, events, or projects.
You're confusing temporary, and anarchistic, with not existing.
From Wikipedia:
The contemporary antifa movement has its roots in the West German Außerparlamentarische Opposition left-wing student movement and largely adopted the aesthetics of the first movement while being ideologically somewhat dissimilar. The first antifa groups in this tradition were founded by the Maoist Communist League in the early 1970s. From the late 1980s, West Germany's squatter scene and left-wing autonomism movement were the main contributors to the new antifa movement and in contrast to the earlier movement had a more anarcho-communist leaning. The contemporary movement has splintered into different groups and factions, including one anti-imperialist and anti-Zionist faction and one anti-German faction who strongly oppose each other, mainly over their views on Israel.
So yeah, antifa is a movement which does periodically have people participate in it. They're just usually temporary and anarchistic.
Likewise with the French Resistance, or Marquis https://en.wikipedia.org/wiki/Maquis_(World_War_II) - yes there were various groups, and they had different structures, some of which were independent detached cells, but at various points some were aided with more official supply, intel, organization, and assistance from allied forces, and required more communication and so some become more "official" due to this. So it was mixed, some completely independent, others less so.
This is part of what makes these organizations effective, and difficult to stop. It's not the same as them not existing.... Not having set and formal national leadership, being temporary, or anarchistic, is not the same as not existing, or having no members.
The hackers known as anonymous all went their separate ways long ago, leaving 4chans anonymous to be little more than a series of social media accounts releasing videos periodically. You say "they released a statement yesterday".... Er... That's all they do. They haven't had any power and members with skill sets since 2008 or so.
...and antifa do exist. Most anarchist are, or are willing to call themselves antifa. A huge number of people used black block (blocking out), and mutual aid to manage, organize, and run the Black Lives Matters riots, and the Portland Corrections protests.
So pretty much the opposite of what you said: Anonymous doesn't really exist beyond constantly releasing statements, and antifa does exist and will most likely take up organizational roles if any long term street protests erupt.
This is also playing on red-shift/blue-shift.
