True, but this isn't your house. If you had a store you'd have to put a "no soliciting", "no browsing", "only X allowed in", etc. if you wanted to be selective. Or, if you had a book for the public to read sitting on a easel on a street corner you would need a notice if you wanted to exclude certain people from reading it.
