Everything you have said except for the last phrase “ sometimes companies are so big they influence the laws themselves“ is false. There are a fantastic amount of regulations in every western country today, many of which are applied arbitrarily or with enough discretion that they are essentially arbitrary. Even the most massive corporations market caps are dwarfed by the monthly spending of government. The only cases where corporations exert the powers if the state over detention and violence are occasions where they do so at the bidding of the state.

It is true that some corporations are so big that they influence lawmakers just as ultra wealthy people always have. Indeed, if corporations were able to do the same things governments did and with the same authority, this process of influencing the government would be unnecessary.
