You actually haven’t seen anyone seriously argue for copyright terms that short?
It has nothing to do with rolling anything back to the early 19th century and everything to do with making copyright policy that maximizes benefit to the public. Remember that copyright is a limit on freedom of expression, that has to be balanced against a significant public good, and that public good is supposed to be encouraging the creation of new works. News services would still want to publish photos even in the copyright terms were one week or one month. A 75 year term is not encouraging the creation of new compelling news photos and is suppressing the sharing of information and the creation of new works.
So there, you’ve seen someone seriously argue for a considerably shorter copyright term than 28 years.
