Make new user sub-folders inherit parent permissions

in case you are newly creating usern (for n > 1), you can do

  sudo adduser --home /home/user1 --ingroup user1 usern

to achieve (1) and (2) and eliminate the need for (4).

one thing that comes to mind is that all these 'usern' will presumably
be sharing the same dotfiles in the user1 home directory, which i
believe are intended to permit each user to customise their
environment to their personal needs and preferences.

this setup will break that per-user configurability.  there may be
workarounds, but the workarounds may be a pita.

are these accounts going to be used by the same meat-user, so to
speak?

if so, this might not be a concern for you.  if not, it might not be
the way to go.

cheers,

ps: i love this topic, btw.  fascinating stuff.
