Wrong? "Theory"?
Since there is nothing in the recent SCOTUS decision that gives corporations the right to select the membership of our governing bodies, then the actual authority in our government still resides with the people IF they choose to exercise that power. There is nothing "wrong" with that statement, nor is there anything theoretical about it. If people CHOOSE to abrogate their authority, choosing to listen only to whatever rhetoric supports their preconceptions, or choosing to simply vote for party name, that in no way negates the FACT that the people are still in authority over who governs - they just are choosing to use lazy, unthinking methods to exercise their authority.
You are trying to make "victims" out of the phenomenon of people not thinking for themselves. Victimization requires force. Without force, there is no victimization. Where is the force in rhetoric? There is none, and rhetoric is all the corporations have in determining who is selected to govern.
Of course, there is also the factor of corruption, which gives corporations and other big money undue influence over those selected to govern. But corruption is not affected one way or the other by applying to all corporations the same constitutional protections as we provide to our media services. Corruption takes place AFTER the selection process is done and over with, and the rhetoric put away until the next election cycle. So regulating the rhetoric will have no effect on the genuine harmful manner big money is operating in government. In fact corruption will never be affected in any way by government regulations of any kind because corruption, by definition, occurs outside of and in spite of any regulations.
As for "wanting" a corporatist state - you are now stooping to the typical demonization of any opinion that does not conform to your totalitarian belief system. (See, two can play at that game.) The corruption of the republican system of government by big money interests is a serious problem. However, crapping on our first amendment is not going to solve it; all that will do is set a precedent for the control of any type of speech or press that is determined to be "harmful" to our system of government. Limiting "harmful" speech or press sounds all rosy - until it is yours that is the next to be defined as harmful.
