I think it's set up to help the people looking at the physical resources they have there (older and rare books on paper mostly), rather than someone looking to work exclusively with an internet connection. If you're not interested in the books, it is of course not a great place to work, though the cafe is pretty good for meetings.

I'm not sure it's really an appropriate place for entrepreneurs unless they are interested in accessing or using the books somehow. When all the other libraries have shut down or turned into Internet access centers, this one will still be valuable as a repository of the books we choose to keep as physical artefacts.
