It's less arbitrary than you think: it's not just about the impracticality, it's about the forced impracticality. Daguerreotypes can't be made any other way than by making a daguerreotype. Palladium prints require palladium printing. TLRs, on the other hand, are just film cameras. They're film cameras that resolve some mechanical difficulties with certain kinds of photographic technique that arose in the 1920s but those difficulties were handily sorted out by the 50s. Nobody who looks at your photos knows you took them with a Rolleiflex. More than that, nobody cares. It's like the Holga movement - nobody gives a shit that you took that picture with a crappy plastic Chinese camera except other hipsters.
So what you're saying is, if you want to be cool, you have to learn how to pull something off that's not so easy to do. I'm on mobile at the moment, but somewhere in my post history is an electronic exhibit of a daguerreotype photo. It's mind boggling how detailed it is, how far you can zoom in. When I get home tonight I'll edit this comment with the link. Edit: Here it is.
