I can place conditions on your entry to my property. If you don't agree to them, then you are there without my permission. And yes, I can call the cops in that situation.

This is quite limited, and for good reason. Most signs that you or I post on our private property have no legal standing. (Even "no gun" signs here in Florida have no legal standing).

The rare exception to this is the "no tresspass" sign. And even those have to be a certain font, color, and location in order to have legal standing.

As individual private property owners, we can still ask them to leave for any reason, and then the law will back us up, but not before.

Corporations have rights

Only individuals have Rights. A creation of a group of individuals (be it a government, or a corporation, or a robot) has no inherent Rights.

A corporation is a US citizen in both the state in which it is incorporated and the state in which it conducts its principle place of business. You can continue to argue with me about this, but you will continue to be wrong.

My law school was the University of Southern California. What was yours?
