It's a lot of work:
1. selecting the worthwhile images
2. cleaning
3. scanning
4. touching up
Other than the scanning step, I don't see how that process is any different from digital photographs captured on a digital camera.
Oh, perhaps you forgot to include the biggest issue

which is the developing, and the ~$10-$15 per roll it costs to purchase the film and develop it after. Probably more now with the increased prices of film.
