Corporations can't exist without some entity enforcing contracts and agreements. That is sometimes the government but it is often also 3rd party arbitrators. In any case though government provides the ultimate backstop.
Most corporations also wouldn't exist without the strong will of a dedicated founder to drive the shared belief and vision of what the corporation could become even when the barriers seemed insurmountable.
Similarly, most corporations wouldn't exist without those early investors willing to stake a portion of their wealth or fund's credibility on those founders.
To a lesser extent, early employees also play a significant role. They take on risk and give up lucrative salaries at larger companies in exchange for more impact on a product and the potential of a big payout down the road.
If any of these entities/groups are not present, the corporation fails. All are needed, not just government.
