The comparison of BitShares to a public company was to demonstrate that unless you call a public company communist you cannot call BitShares communist and hence the propagandising basis of OP and much of this thread has been debunked, so I think it was productive to make that comparison.
If a single corporation ran the entire economy, then yes, it would be Communism. Communism is a highly elitist, hierarchical, centralized system of control which disenfranchises the people (aka stakeholders) to empower the ruling party (aka 101 delegates). Communism is best described as
STATE CAPITALISM. I agree with Stan that Bitshares is a company, but it is a company that commands complete control over the Bitshares' economy. This is why Bitshares is Communist.
As Vladimir Lenin stated:"We recognise and will continue to recognise only state capitalism, and it is we — we conscious workers, we Communists — who are the state. That is why we should brand as good-for-nothing Communists those who have failed to understand their task of restricting, curbing, checking and catching red-handed and inflicting exemplary chastisement on any kind of capitalism that goes beyond the framework of state capitalism in our meaning of the concept and tasks of the state."Bitshares is identical to Communism. Unless you are a part of the "ruling class" (aka 101 delegates), you are subject to taxation via inflation.
"The way to crush the bourgeoisie is to grind them between the millstones of taxation and inflation." - Vladimir Lenin These 101 delegates use their power to maintain a stranglehold on the system by taxing competing businesses and shareholders. Lenin once again describes such a system as
“nothing but state capitalist monopoly made to benefit the whole people." The fallacy of such a statement is that it only benefits the "new master class" (aka 101 delegates).
This does not make BitShares centralized as 'Decentralized' and 'company' are not two mutually exclusive terms, that would be like arguing Bitcoin is centralized because the currencies preceding it were centralized.
Bitshares is a centrally administered corporation which controls the entire economy. As I have said before, the delegates use their stake to maintain their position and form a monopoly over the system. This is not a system which promotes free enterprise, but is the very definition of Supercapitalism (aka Crony Capitalism).
