I'm not convinced it's a given it will. If it becomes necessary to license, owning the large publishers will be leverage and allow locking competitors out unless you have a portfolio to cross license.

OpenAI alone has a market cap that'd allow it to buy about as large a proportion of publishers of newspapers and books as they'd be allowed before competition watchdogs will start refusing consent.

Put another way:

If I was a VC with deep pockets investing in AI at this point, I'd hedge by starting to buy strategic stakes in media companies.
