I don't think that Hollywood would end literally. Studio headquarters would probably remain in Los Angeles, Academy and other awards shows will be held there and some people would stil earn money through guided tours of former stars' homes.
But Hollywood as the synonim for US film industry will probably end. Film and TV shows being produced by small number of large centralised corporate entities will be replaced with more decentralised structures based on smaller companies, streaming and international markets.
