This can be done, and has been done since early cinema, by making the film essentially a stage play. This definitely can make for some excellent films! It focuses the production on the story, and most of the time of evocation of out-of-scene activity. But your point highlights the opposite: merely having fewer people in the scene to save money without considering what it actually takes to make it work. Even Blum gets this right; these bigger productions have no excuse except laziness. And in my case it's led to me simply watching less video, because it's boring.
