See, I think what this is about is psychology and expectation.

Back in 2000, the alternative to shooting film was prohibitively expensive digital cameras that had only just emerged; people had not grown up with digital and so digital was an unfamiliar, largely inconvenient alternative (because people didn't really have decent computers and Photoshop was still in its infancy)

In 2022, this situation is almost entirely reversed. Everyone has grown up with digital cameras, and everybody is at least aware of the existence of photo editing software. Digital cameras can be dirt cheap, and film cameras have become the unfamiliar, largely inconvenient alternative (because one hour photo labs have all but ceased to exist).

In 2000, analogue was the cheaper alternative, even though it still cost money. In 2022, digital is the cheaper alternative because it's effectively free.

So shooting film FEELS expensive even though it isn't, because in 2000 paying for film/processing was a normal living expense, but the hipsters getting into analogue now have already set that living expense aside for avocado toast or whatever the media says now.
