Unless you would like to argue that no true Scotsman would ever abuse a position to make a buck...
Because the state has colluded with certain companies to remove the 'free' from the above statement, the US internet is no longer a capitalistic system.
Your statement about all capitalism eventual collapsing to fascism deserves more evidence. If you could truly prove your point, you'd win a nobel prize.
The prerequisite to purchasing government actions is the government having the power/authority to take action. There's a reason lobbyists do not approach you or me.
Getting rid of government doesn't change the ability for the powerful to use money to apply coercive force against the powerless. You know that, right? It just means they have to do it themselves. Would you rather $EVIL_CORP own a Senator or own weapons of mass destruction?
Absent the government I'm not even certain there would be weapons of mass destruction. It is the state who demands these weapons to maintain its monopoly on force.
A business, on the other hand, is interested in making a profit. Absent government coercion, a business must provide a worthwhile good/service to make a profit, all while competing in the marketplace.
Anything an "$EVIL_CORP" might do pales in comparison to actions we know governments have done. One must only tally up the hundreds of millions of lives lost during the 20th century in senseless wars, democide, etc.
