It exists already:
du -s --files0-from=F
>From --help/man output:
--files0-from=F summarize disk usage of the NUL-terminated file
names specified in file F
Note that the files in F have to be \0-separated.
As long as your file.txt doesn't contain any names with
embedded newlines, you can convert it like this:
tr '\n' '\0' < file.txt > file0.txt
then do this:
du -s --files0-from=file0.txt
