Actually, individual states do have limits on free speech, like laws against libel and slander.
Individual states do have rules on unreasonable search and seizure, which cannot be less favorable than federal rules, but can be more favorable. In cases like that, the federal rules form a floor through which rights cannot be limited, not a ceiling disallowing greater rights.
Individual states limit the rights of property owners via zoning laws, laws restricting building on soil that won't percolate, etc.
I cannot think of any constitutional right that is absolute.
Can you?
