But what the corporation cannot do is put you in jail, seize your assets, prevent you from starting a business, dictate what you can or can't do with your home etc.
a corporation can "put me in jail" for copyright violations, accuse me of criminal conduct (happened in the UK, took them years to fix), seize my money (paypal, etc), destroy my business (amazon, google)...
But government is far more of a potential threat to liberty than the most "powerful" corporation could ever be.
you (in the US) should vote for a better government. i'll trust my government to protect my liberty over most corporations any day.
