Absolutely, but many people do not have the time luxury to read dense theory books, and (good) podcasts can at least get people acquainted with the ideas.

Also, (and I’m putting words in your mouth, so sorry for that) I think it’s a fallacy to say that every comrade must be a theory scholar. Certainly our leaders and organizers should be, but I think it’s fine if people don’t have the academic inclination and want to contribute in other ways.
