Just because a place hosts culture, it doesn't mean that you are entitled for it. For example new movies are pay of culture, but that doesn't mean you should sneak in to a theater without buying a ticket because every movie theater requires paying. Compensating creators for their work is a part of experiencing creative works that are culturally relevant.

The US constitution absolutely does recognize that the public is entitled to all cultural works, which is why copyright is required to be time limited.
