Capitalism does not lend itself to massive international corporations wielding as much power as governments themselves. That only comes from government involvement to begin with - the corporate personhood that enables bad actors to be shielded from their behaviors, to grow their fiefdoms beyond controllable range and crush small business - that is enabled by government.

The corruption of capitalist systems into corporate oligarchies is a process of leftist subversion, the beginning stages of the original definition of fascism - the merger of state and corporate power.
