This may be correct only in the sense that, without a government, there would be zero liability (instead of limited liability) for big companies. After all who could go against, for example, Microsoft if it decided to screw their customers and suppliers?
Even the largest companies are dependent on maintaining their reputations as organizations which uphold their ends of any agreements. A company which no one will contract with might as well not exist. They're not going to just turn outlaw and repudiate their liability as determined by a fair arbitration process; that would be tantamount to corporate suicide.
