So I was able to recreate my issue. Your method worked at these 
functions, but then the issue propagates to `require's for packages not 
installed. (Every once in a while I switch OS', and simultaneously am 
sitting down somewhere without an internet connection.)

I imagine putting `ignore-errors' at every `require' would be bad form.

Maybe I can start up Emacs with an option to ignore errors? "In 
pseudocode",

    emacs --ignore-errors

Or even better, maybe I can have in my init file, a line to check for a 
connection, and if there is none, prompt me to allow a global 
`ignore-errors'. Or no prompt, but give a message that it occurred.

PS

Thank you for the code improvement, I did not notice it the first time,

(when (notevery (lambda (pkg (or (package-installed-p pkg)
                              (assoc pkg package-archive-contents))))
                pkgs-2b-present)
  (ignore-errors (package-refresh-contents)))
