Personally, that just feels like semantics to me. They’re a structured group of people that exists to generate profit. Whether they technically meet the definition of a corporation doesn’t change what they’d be like under anarcho-capitalism.
Yes, shockingly, the definitions of words are semantics!
And to literally ask if something meets a definition then try to dismiss the response as semantic while offering your own incorrect definition is fantastically silly.
Gangs are structured groups of people that exist to generate profit illegally.
Unincorporated businesses are structured groups of people that exist to generate profit legally.
Incorporated businesses are structured groups of people that exist to generate profit legally with the special legal status of personhood.
Part of the point @mark3748@sh.itjust.works was making is that corporations are nearly identical to other organizations, even illegal ones, except they have a legal status that lets them do far more damage.
