>How are corporations just not like states?
They aren't coercive in nature.
>How are they just not another hierarchical institutions that need to be abolished?
Definition of hierarchy, according to http://www.thefreedictionary.com/hierarchy
>1. A group of persons or things organized into successive ranks or grades with each level subordinate to the one above: a career spent moving up through the military hierarchy.
You can't completely abolish hierarchies if you define it this loosely, not without also abolishing freedom. If one person decides to take orders from another person, do you want to step in and threaten both of them with a gun? Congrats, you just created a new hierarchy, wherein your judgement on what is beneficial stands above the autonomy of everyone else.
>And how exactly would we reduce corporate power if we got rid of government?
By not inflating it further. No regulation that only hurts small businesses who can't afford an army of lobbyists and lawyers. No taxation that cripples smaller businesses. No subsidies that support corporations, whether they have fucked up or not, at the expense of the taxpaying population. No bailouts that prevent big, unsuccessfull businesses from making way for smaller, more innovative and competent ones. No copyright laws that stiffle innovation and are used as weapons to harass your competitors.
>And isn't less regulation just what they want?
If it is, then why don't I see Microsoft pushing for anarchocapitalism?
>inb4 because even Microsoft sees that it's a stupid idea
Why would it be a stupid idea for Microsoft? I thought corporations only cared about what's best for them? If anarchocapitalism would mean that the rich would get away with everything, then why isn't Microsoft proposing it?
